Put in a new core support for this 68 restoration with new wire harness. My old core support had two ground wires located on the driver side (next to voltage reg.), one from the wire harness and I've got that okay but where does the second one go to? Thank you!
The 68 is a different animal than my 67 but this may help. If the voltage regulator is attached to the radiator support with well-nuts it needs a ground wire. The pictures in this post shows that ground.
