A bit of an update.
After much procrastination from my mechanic friend, his auto electrician friend finally finished rewiring my body harness. He only worked on the car during his spare time so it took awhile.
The wires were so bad that they had to remove the computer box and start rewiring from there. Under the computer box, the wires were
NOT degraded, so the heat didnt do its damage in that area.
While I was at the electricians shop, he had other cars in there with wiring problems worse than my car. One was a first gen Lexus IS that had bad wiring all over the engine bay, and even worse, the problems continue inside the car, having to remove the dashboard completely, as well as the center console. The amount of wires needed to be replaced was simply ridiculous that the electrician simply laughed at "my wiring problems" and said "compared to modern cars with all the wires that they have, yours look like a piece of cake".
You hear that people? your much dreaded 600 wiring problems are nothing but a small fish in a big pond now compared to modern vehicles. Which makes all the more hilarious when people here spread FUD at how rewiring a 600 is like rewiring a Space Shuttle. Please....
Total cost of parts and labor for the rewire was.... lets just say its under a grand :thumbsup:
The car is still a long way to go from what I would consider "restored", but its biggest achilles heel is finally fixed and everything else seems peanuts in comparison.
As a souvenir, the electrician gave me some of the old MAF wiring:
You can see where the previous owner/mechanic(?) tried splicing the degraded harness with new wires, which didnt work out as planned. The electrician mentioned this bundle is only a small portion of the total amount of wires he replaced, which if you look at my original post in this thread, rings true.
Upon startup, the idle is smooth as silk and quiet like a motor turned off, which was a far cry from how it used to run prior to fixing the harness. I didnt get a chance to drive the car, but I did let it run for a good 5 minutes while testing out certain things and I was left impressed.
Its a bit of a heartbreaking moment knowing I cant drive the car for another couple of months while it undergoes restoration. That V12 is quite the potent drug I tell ya
