Pops and I building a 49 f6 rat rod style. Got 06 axles under it, BTS e40d, and a 700hp 12v. ( he wanted to do a 12v haha ). Anyways, I got a question on trans set up. I want a ratchet shifter, but then still need it programmable for shifting. PCS is what I was looking at but do I need a harness...
