Hmm I didnt know Scotty had a harness. I already wired the neutral safety switch in hence the car running. Reverse lights shouldn't be too bad. Already ran the pigtails under the dash, just need to find where to splice into. If the TCU has wiring for the reverse I could alway splice into that when I go ahead and remove it tomorrow.

Thanks for the words of wisdom! I should have the car completely back together tomorrow morning as long as I dont run into any unforeseen issues. (Like me sawing into a coolant line haha)
