I bought a psi harness and it's made for an 80e but I'm going to use a 65e.
What do I need to do to make it work?
Anyone know precisely what needs to be done?

I know Lt1swap has a guide to swap from 4l60e to 4l80e of the TCM cable. So you can just do the reverse of what it says. i think it only 2 wires moved.

I used http://my-efi.com/ the guy charges $300 to make your harness to stand alone. Very cheap and he does excellent work.

Jake, that has nothing to do with my question.
Shaggy, I may have to just do that.
I called psi and they said they would fix it for $25 to use a 60/65e
I know it can't be hard, I guess I better start looking into this as no one goes 80e to 60e

If the PSI harness was directly purchased. A phone call to them might save you the troubleshooting. Just tell them plans change.
