Psi, I am going to be purchasing a Psi harness for my next swap. (ls1 67 gto) I have been using a different company and have not been satisfied at the things they leave out. (sometimes a/c or alt and other things) How is the park neutral switch wired in this harness? On the trans or built for column? using a 411 pcm. I have heard good things about Psi.
