Any thoughts on what the connector below goes to? it mounted against the firewall near the C100 I am getting ready to install a new wiring harness from painless and in the process trying to remove anything thats unnecessary or no longer on the car. The POs molestedjust about every inch of this car. The search results I found said that it could be the fuel relay or a fan relay does anyone know for certain?

attached is a picture of the conector/relay

Z-8247TRW 14078915

 

P/N 14078915 seems to be a fuel pump or AIR control relay. GM uses the same relay for a lot of different functions.

It would be better to go by the existing wire colors that are connected to the relay to determine what its function is.

Get out your wiring diagram/schematic.
