http://psiconversion.com/tech_articl...structions.pdf http://psiconversion.com/tech_articl...STRUCTIONS.pdf they show the 6L80/6L90being wired up like the 4L60/80s, but they should be wired up opposite. The TCC wire receives 12V when the brakes are pushed (brake lights activated). Like this:

Re: PSI wiring Harnesses
I'm glad to see such positive responses on the PSI harness! I ordered my harness a couple weeks ago from Texas Speed. I wish I would have waited!
