I picked up 1979 300D and trying to get it started. I installed new #3 gauge Hot wire Battery lead to starter and cleaned wiring harness attached to soleniod. I noticed that it had three yellow wires attached but the red wire had been cut off. I don't know where that is supposed to go. Waiting for Wiring diagram from MBUSA. Car has remote starter button to the left of the steering column. I don't know if that is standard install or add-on.
I had glow pulg lite before I changed terminal now I don't Any suggestions?
