I'm having some electrical issues that have me baffled. I did a 4 cyl. auto to 5 speed V8. Had some ground issues in the past but everything worked. Now with a new motor and ground fixed...got some strange gremlins. The safety wire on the clutch(the black one I think) works fine. But if I hook up the white one, the activation of this circuit makes the car dip then surge when the clutch is let out. What is menat to do. The other problem is when I put the car in reverse, that trigger for the rev lights makes the starter crank. For now, both of these problems are unplugged, and all is well, but I would love to figure this out.
