1999 Camaro
1. Red conn., #53, spark retard signal
2. Blue conn.,# 8, TPS 5v reference
What should I do with them? Thanks

red con. #53 not needed
blue con.#8 is the 5v ref for throttle position sensor this is needed the pcm monitors this and should be ran to the plug

A-gry c1 blue\#46 5v ref
B-blk c1 blue\#54 sensor ground
C-drk blu c2 red\#24 sensor signal
