Starting system
I have a thread rolling on s197 forum regarding this problem and I will duplicate a thread covering the basics.
I replaced the BEC thinking that was my problem, apparently not, it's somewhere in the signal wire that comes from the clutch switch and leads to the pcm/bec, I can't pull up the wiring diagram on my phone and computer from iihs.net for some reason. So all I did to see if it would work was make my own standalone relay which worked and the car cranks so much better as well. However the haynes manual(vague with their wiring diagrams) says the starting system does pass through the pcm, this is clearly a poor wiring connection or a short. If someone could tell me the wire color going from the clutch switch to the bec on a 05 v6 car (engine swap) or copy and paste it that would help me so I can do a proper resistance test. It's a violet/red wire leading out of the clutch switch, but my haynes manual says white/pink( like I said vague diagram since it doesnt get model year specific).
