Default 4l60e to 4l80e swap
I have a 2003 Chevy Silverado 1500 5.3 extended cab 2WD with 4l60e in the future I'll plan on swapping to an lq4 with abound 400-450hp and would like to swap to the 4l80e.

I'm trying to figure out what I would need for the wiring and to mount it in my Silverado.

Why not just get the complete LQ4/4L80e pullout with PCM and wiring? Will save you a little trouble.

what joe said. I imagine if you get it from same like model year it would be a simple bolt in swap.
