01 / F01 CABIN PLUG
The easiest installation. The smallest reason for confidence.
The Cabin Plug is the one in the photograph: one little box, one switch and an accessory-socket plug. It is our easiest-to-install, least-effective catalog tier. I am describing the lineup's intended hierarchy, not reporting a measured EMP result. We have no whole-vehicle test data establishing an effectiveness ranking for these particular boxes. That distinction has caused several difficulties at the slogan meeting.
A properly designed outlet suppressor can clamp transients on the accessible 12 V circuit. It is connected through the outlet's wiring, fuse and potentially a switched supply. Those paths affect how much it can influence other nodes. If the socket is disconnected when the car is off, a plugged-in device does not acquire telepathy to compensate. A glowing LED establishes that an LED has been funded.
An EMP field can induce stress into wiring elsewhere in the vehicle. A sensor lead is not obliged to return its first dangerous transient to the battery or the accessory socket. Distributed coupling is the core problem: the exposure, wiring geometry, impedances and individual interfaces matter. My connection maps are conceptual engineering analysis, not teardowns of the pictured products.[1]
The people who say they are impossible to fool keep buying things because the light came on. I would like us to attempt a second test.
02 / F01B BATTERY CLAMP
Closer to the battery. Still not everywhere in the car.
The Battery Clamp is the next tier: a simple box with short leads attached at the battery. A suitable suppressor here addresses the main supply node more directly than a remote accessory outlet. A voltage regulator maintains a supply; a transient suppressor limits a brief overvoltage. Calling both “regulation” makes the brochure easier and the engineering discussion worse.
Short connections and suitable clamping characteristics matter. The installation, pulse and impedances still determine residual stress. Protecting a battery terminal is not evidence that every ECU pin, sensor input or local ground stayed safe. A pulse induced near a module can stress that interface without first asking the battery for permission. Sales has proposed a permission system. I have proposed that Sales stop attending the waveform review.
Two connection points, not two force fields
OPEN FULL-SIZE BENCH SKETCH ↗So yes, this is a more credible place to address the main 12 V rail. No, it is not a quarter-mile force field. The shelter accepting an F01-series credential proves that the elevator recognizes the credential. Our access-control reader is not an EMP laboratory.*
03 / F01D OBD-II
A diagnostic port is not a back door into every volt.
The OBD-II edition can stand alone or supplement either other edition. The cart should not force you to buy a battery unit to own a port unit. I will not allow that ordinary purchasing option to be mistaken for evidence that all three together protect the whole car.
A typical 12 V Type A diagnostic connector includes battery power at pin 16, ground connections, and communication pins. CAN uses pins 6 and 14 where that protocol is implemented. It does not present a dedicated connection to every module's internal 5 V or 3.3 V supply. Reading a message from an ECU is not being electrically connected across the ECU's private power rail.[3]
The OBD port exposes connections, not every internal rail
OPEN FULL-SIZE BENCH SKETCH ↗The actual pins connected inside a protection device matter. An OBD-shaped enclosure does not prove it protects CAN at all. Faraday Defense describes T.R.A.P.-OBD2 as a port transient device within a multipoint kit. That published description must not be expanded into an imaginary direct connection to all low-voltage supplies.[4]
Thin communication wires alone do not make transient protection impossible. Local TVS components can protect CAN interfaces when selected for the pulse current, clamping voltage and transceiver ratings, without inappropriate loading of the data bus. Capacitance and layout matter too. Texas Instruments distinguishes the protection component's rating from the assembled system's rating. Its interface ESD examples are not whole-car HEMP qualifications.[5]
ANACHRONISM REMOVED / F03
While I was down here, I took the OBD photograph off the Heritage 112 MPG Eco Chip. Grandfather's engine sketch predates OBD-II. An old carbureted engine does not gain a diagnostic port because Marketing found a convenient stock shape. The Heritage package now has plain leads and a workshop bracket. That fixes the period mismatch. It does not prove 112 MPG. I still want the fuel-consumption test.
04 / KNOW THE DIFFERENCE BETWEEN A REGULATOR AND AN ISOLATION BARRIER
Five volts is not another dimension.
A module can regulate 12 V down to 5 V or 3.3 V while sharing the original ground. That is not galvanic isolation. Some architectures deliberately isolate power and communications; others do not. Texas Instruments' isolated CAN example uses an isolator and an isolated supply, alongside a regulator for the non-isolated supply. You need the circuit architecture, not a list of voltages.[2]
A lower voltage does not prove an isolation barrier
OPEN FULL-SIZE BENCH SKETCH ↗A battery clamp is not automatically a clamp across an isolated output. An isolated interface also has a finite withstand capability; “isolated” does not mean “invulnerable.” The sensible question is what stress reaches each sensitive power, data, sensor and ground connection under the defined threat. The question I keep receiving is whether the upgraded certificate comes in copper foil.
05 / THE ACTUAL WORK, WHICH THE STOREFRONT DOES NOT EXPLAIN
Protect the paths. Test the system.
Better resilience can combine shielding, bonding, protected entries, local suppression and appropriate isolation. A shield has to work across seams, closures and service penetrations. Cable shields need effective terminations. External lamps and other awkward interfaces need an appropriate boundary design. “Put an isolator on it” is not a complete answer.[1]
The openings are part of the shielding problem
OPEN FULL-SIZE BENCH SKETCH ↗A custom vehicle barrier would also have to address its windows with appropriately integrated conductive glazing or mesh, doors, vents and wiring penetrations. Ordinary dark tint is not a shielding qualification. A steel shipping container is not automatically a tested enclosure. I know it looks reassuring. So does the man who sells the container.
| Option | Reason to consider it | The part people skip |
|---|---|---|
| F01 Cabin Plug | Very convenient accessible supply connection. | Outlet wiring and switching; no demonstrated protection for all other interfaces. |
| F01B Battery Clamp | More direct access to the main supply node. | Local sensor/data stresses and separate power domains are not automatically covered. |
| F01D OBD-II | Standalone port access or an additional protection location. | Actual connected pins and topology; no universal access to internal ECU rails. |
| Protected spare modules | A possible recovery strategy. | Shield performance, compatible parts, programming, immobilizer pairing, tools and somebody who can use them. |
| Whole-car enclosure | Reduced field exposure inside a closed barrier. | Measured assembled performance. The parked car does not retain the enclosure when it drives away. |
| Vehicle hardening | Addresses multiple identified entry paths. | Threat definition, installed-system tests, safety integration and maintenance. Very different from collecting impressive component ratings. |
Mission Darkness offers a vehicle-sized enclosure with a liner, door system and filtered connections. That is a manufacturer-described alternative, not my independent certification of its performance.[6] Ask for the report: waveform, field strength, installation, operating state, ports tested, residual stress and pass criteria. “Military grade” is not a waveform.
The 2008 EMP Commission report tested 37 cars from 1986–2002 and found mixed outcomes: nuisance behavior, stalls and one damaged dashboard; eight cars showed no anomalous response. Testing stopped for a car after an anomaly. It does not establish that every current car will fail, or that every current car is safe. Fuel, roads and services remain dependencies even if the car survives.[7] Evidence is untidy. Panic is easier to put in a shopping cart.
06 / MANAGEMENT HAS MISTAKEN LIMITATIONS FOR A PRODUCT ROADMAP
The car works best when nobody uses it.
My recommendation was to define a realistic threat and test the relevant interfaces. Management asked how much larger the enclosure could become before the customer noticed it had replaced transportation.
The Backup Parts Pantry
$18,999 planning allowance
Compatible spare ECUs, relays and sensors in a qualified enclosure. Add the tools, programming plan and skill to fit them. Management's premium kit includes a card saying “YOU SHOULD HAVE LEARNED THIS BEFORE THE EVENT.”
The protected spare is useful only if the recovery plan works.
The Park-It-And-Remain-Calm Pavilion
$249,999 before land & maintenance
A giant Faraday enclosure that holds the entire parked car. Qualified seams, doors and service entries. Maximum confidence requires leaving it inside. Driving to work has been reclassified as a threat-seeking behavior.
Your car is safe from commuting, subject to the enclosure's measured scope.
The Personal Automotive Sarcophagus
$899,999 vehicle-specific engineering allowance
A custom outer barrier with integrated conductive windows, seals, protected openings and services. Every door closure becomes an inspection event. The warranty excludes the owner's recurring need to see out.
A tire change now begins with a containment meeting.
Procurement concepts / Finance's figures are considerably better developed than the hardware.*
THE 1903 EXECUTIVE / DELETION EDITION
LESS CAR.
MORE CONTRABAND COAL.
The proposed 1903 Executive Deletion Edition has a hand crank, mechanical controls, a wooden bench and no electronics. No ECU, electronic ignition, infotainment, air conditioning, power windows, navigation or heated anything. Cruise control is your ankle. Weather enters through the Weather Admission System, previously known as the absence of a roof. The fuel gauge is a stick.
The 1903 Executive
OPEN FULL-SIZE PHOTOGRAPH ↗Removing electronics reduces one class of dependency. It does not prove EMP immunity, create a fuel supply or cure an unsafe vehicle. Management heard “fewer electronic systems” and removed the safety package too. The reversing assistant is now an employee standing behind the car, gradually losing confidence.
Why does this miserable thing still cost $89,900? This particular new-build plan refuses the applicable emissions conformity and modern vehicle-safety certification. As specified, it is not a lawful compliant road-car offering. An antique date on the brochure does not turn a newly made car into an original antique. There are configuration-specific rules and exceptions; “we hid the factory” is not one of them.[8][9]
Accordingly, management insists that every part be made by hand in an inefficient forge inside an underground bunker. The forge does not meet EPA requirements. It has no emissions control, no credible permit file and an exhaust stack described in the equipment register as “a suspicious geological feature.” The foreman considers the ability to waste enormous amounts of heat a form of industrial sovereignty.
Hand-made, repeatedly
OPEN FULL-SIZE RECOVERED SKETCH ↗Location security review
OPEN FULL-SIZE RECOVERED SKETCH ↗Nearly everything gets heated, hammered wrong, reheated and hammered again. The forge burns so much illegal coal that the car is practically a souvenir from the coal-smuggling operation. No outsourced castings. No efficient furnace. No creature comforts. Just hand-made parts and an enormous contraband-fuel bill. Paying for a simple car would be much cheaper. That was my first objection, and the only sentence removed from the cost meeting's minutes.
The premium coal delivery service
OPEN FULL-SIZE PHOTOGRAPH ↗| Finance's explanation | Amount |
|---|---|
| Metal, mechanical parts and regrettable bench | $6,900 |
| Hand forging, rework and patriotic heat loss | $17,000 |
| Enormous amount of undocumented coal | $22,000 |
| Smuggling that coal to the bunker | $44,000 |
| Total / the car is the incidental deliverable | $89,900 |
That is $66,000 for coal and getting coal somewhere it should not be. The illegal-coal line alone could buy a substantially more comfortable transportation problem. Management says the inefficiency is essential because the inventor refuses to let the government learn how poorly his furnace works.
$399/month Historical Continuity License. Royalties fund the inventor and the courier delivering unmarked currency, supplies and another coal invoice to the bunker. The hand crank does not need a subscription. The smuggler's second mortgage does. Cancelling will not disable the car; it will cause an exceptionally long handwritten letter about loyalty.*
I believe in suppressed documents. I believe in testing. I do not believe that stripping everything useful out of a car becomes engineering merely because the receipt is classified.
