Hey guys...searched and I have been piecing together my powertrain swap for years....just through a divorce and now I need to pick it up again...anyways, can I get a whole harness to convert? I actually bought a FRPP one a few years back...I still have it...BUT..I heard it is only 1 of 3 harnesses?
