was wondering. i have a ae86 Gts. this guy i bought it off of managed to cut a lot of wires from the harness and its a pain just trying to figure out the color coding on the diagrams...can i just switch the whole harness with a new/used one? body is straight and clean just only thing is the wiring harness...and i know the harness is the easiest thing to change, i can do it in a whole day. only because the cluster doesnt work and i have to start the car with some switches he hard wired seperatley. also keep getting this buzzing sound from a relay in the driver side kick panel whenever i turn on the running lights with the light switch....what ya'll think?
