Default LS1 Swapping C4
New to this site so I hope this is in the right forum.
I'm currently looking into LS1 swapping a C4, and had a question about the wiring harness. If I use a manual transmission, does it matter what harness I get? For example, if I get a harness meant for say a 4l60 and just not wire the transmission stuff, would the vehicle be operable? Any other advice or tips for LS1 swapping would be much appreciated. Thanks!

Buy a harness made for a swap. Or get the donor harness a wiring manual and shorten or lengthen as necessary.
