Just bought 91 z28, need wiring info




found a wire connector screwed to driver side fender then these 2 little wires about 8 inch away. Traced them down to where they intersect with main harness. Are they supposed to be grounded to that terminal? Thank you guys!

Yep, that's the cruise control ground. In some years it's also the ground for the fog lights, but by 91 the fog lights are wired into the headlight/parking light harness.
