Question 4l80e harness swap to 4l60e possible?

Good morning PT,

Few questions i have recently installed a 2006 5.3l/60e with matching PCM into a 84C10 ok.
But the wiring harness i used was out of a 2006 2500 lq4/80e, the truck turns on turnkey no problems and can even drive up/down my backyard. But the transmission isnt right, i know the 60e harness has different pins you usually switch positions when doing a 80e(i.e. Pins 22/23)swap.

So my question is, do i do the opposite since i have the 80e harness swaping to a 60e tranny? Or can i just get it tuned?
Thank you,
GOD BLESS

I just did a 60e to 80e swap and your looking to use a 80e harness on a 60e. Right? If so I think you would just switch the white and brown wire on the big plug, and disregard the front speed sensor (wires 22 and 23).

That's what I would do, it would be reverse of doing a 60e to 80e swap.
