88 anti-theft control module issues
 

My alternator light is flickering. and I just had the alt rebuild...

So what’s the reason the wiring from the warning light goes to the anti-theft control module before it gets to the alternator on an 86-89?

porsche did a lot of strange stuff with wiring. the AC relay is wired thru the starter solenoid.
this is a big one to me. they fused the wiring AFTER switches. fuses are there to protect the wiring and there is a lot of wiring in the dash that is not protected. with our wiring getting brittle and shorting out, now the wires just melt and burn instead of a fuse blowing.

Wiring.
 

I had a look at the factory manual, and have not a clue.

Also, having added a few electrical upgrades, I am in total agreement with
T77911s.

Good luck,

Gerry
