Lots of wiring issues, but FINALLY I have brake, backup, flashers, turn signals and dash lights!

I have 2 - 1in pipe to/from the radiator running thru the tunnel and wasn't sure how much heat it would give off. Right now, it is warm and the engine is keeping at 180-190. Thru the tunnel, minimizes the 90 deg bends, but I think running along the longs or IN the longs would of worked, but would have been more work to install. The water pump is strong and will pump thru several bends with out issue.
