Getting everything ready for my ls1 swap and may have gotten a little hasty. I have a printout of my pinouts and I'm seeing that both the tan/white wires in the picture get connected back together to be run through the c100 and back to the fuel pump? And that leaves the green wire to be put into my new ECM to control the three second pressurize?

RED: Ignition switch
ORANGE: Fused power
Black/white: Ground
Tan/white: to C100, then to fuel pump?
Green: ECM?


P.S. I may have the usage of the red and tan/white wires mixed up as the pinout just says "fuel control" for both.

 

Red, prime test connector. Leave this d/c
ORN, fused 12v batt to the relay
Blk/Wht, grd
Tan/Wht, fuel pump 12v
Dk grn/Wht, PCM


Also, since you've got it off, Id suggest trashing the flat style relay/socket and upgrading to the newer oval style. Youll find them on most 90's GM car/vans. The flat style is prone to exposed wire issues leading to shorts and general mayhem

 

Ok, thanks pocket.

And the relay you speak of, does it look similar to the fan relays in third gens?

 

Itll be one of these, most likely the one on the right with different colors
