Ok, Im needing help finding someone that can convert a 5.3 truck harness to be stand alone and be as plug-n-play as possible. Im throwing the engine in a Foxbody this spring. But all I can find are people that sell completely new harnesses for $500+. So if anyone knows of a company or person that will convert my stock harness for a fair price and do a good job please PM me or post up the info in here. Thanks a million guys.
