from what I understand, I believe ORS also asks for both the 3.0 and the 3.4 harnesses as a core. they may or may not use your wires to make the harness.

I'll be offering both harnesses for mamual tranmissions and also auto transmissions. the automatic harnesses have more wires that are necessary than the manual harness.

its better to have the original harnesses from the 2 vehicles in order to construct the harness. the harnesses will be made according to the specifications of the swap, wiring maybe different from year to year.

we will test all the connectivity of the wires before we construct the harness, so that we do not get a damaged harness as a core.
