Mystery wiring and switches

[Mixed76]

Hi everyone,

I have these mystery switches in the driver's door of my 912e. Other than the engine, which is from a 1978 SC, and the minimalist stereo, the car seems relatively unmodified down to the 14" fuchs.



The attached wiring in the door is way longer than it needs to be and includes this solenoid looking thing.



Has anyone seen this before or know what it might be? I haven't traced the wires into the dash yet. The speaker wires are black and red and run separately; the other door is the same, just a single speaker.

Obligatory car picture:



Thanks much

That's a curious find Mixed. Am looking forward to you tracing those wires to their ends.

Power antenna.

Or part of an alarm?

I have no clue on what the switches and relay do but I am curious what there functions are. I hope you take the time to trace out each wire and draw a schematic of where the wires tie into the cars original wiring.

The small clear covered device looks like a speaker cross-over. Maybe had a coaxial speaker and split the input on the speaker itself.

This would be a fun read.

I looked up the acronyms to help shed some light in the switch panel usage.
So according to the web, the abbreviations are:

IMP: It's My Party

SOC: Space Operations Command

TCH: Turbo or Thermal Conduction Heating

Looks like a nice car, I would check all the wiring after looking at that mess.

Is it possible all those were wired to 1 gauge so that the function of the gauge was selected by the toggles?

IMP : Intake Manifold Pressure
SOC: State of charge
TCH : Tachometer

The device in your hand is a relay. You can clearly see the coil, contacts, and the clip on top holds the relay to the base.
You might take a deeper look into all the wiring associated with this. It looks dodgy.

Must have been owned by an electrical engineer;(

Sorry for no follow up, I didn't see and pelican didn't tell me!

One of the previous owners worked for Raytheon, maybe it's his work. I thought TCH might be tach but the others had me stumped. I will play around more and report back.
