I have a '53 GMC 100 with a '56 Chevy 235 in it that is (hopefully) going to be rewired. I have a Jim Carter basic harness and would like to try to install it myself. Electrical work IS NOT my forte. Any tips on going about this? Do I rip all the existing wiring off and start from scratch or try to replace one wire at a time? Start under the hood or under the dash?
Thanks in advance for the help.
