No wipers and brake lights.

tsk tsk tsk.... Honestly I'd get to looking at the junkyard and grab a new unaltered harness. At the yard here in town I was was able to grab the ENTIRE '01 Tahoe harness plus fuse block for $20 on 1/2 off day. It shouldn't cost all that much, plus it saves you quite a bit of headache. Did you only get rid of the underhood portion of it?

Honestly, I have no idea why there is a relay for my brakes in that truck. I found out Saturday that it was never even hooked to my brakes. I put a test light on my chassis harness and got the brake lights working in about 10 minutes. They were not working due to a disconnected wire, not related to the LS swap, I guess I have been without brake lights for some time now and did not know it. I still need to rewire in my wipers. I have the diagram for them, but this is going to be a little more involved than the brake issue.
