Good evening
Have a 96 1500 single cab that I am swapping in a 5.7. Originally the truck was a V6. Stole the motor and the engine wiring harness out of a 97 Tahoe. Everything went in and put power to it all and realized the third brake light was on as soon as everything had power and now have no brake lights. Look into the fuse box and there is no wiring to the relay for the brake lights. Any reason for that? Didn't think the wiring would be any different between the two trucks besides the slight differences for the motor. Do still have the V6 wiring if need to splice some stuff in but just curious if I'm missing something, if it's somewhere else, or if just this harness is missing it for some reason.
