Because of my setup with my engine and S/C I have decided to get the XFI Fast stand alone fuel management system. I have completely rewired the fans, TCC, Fuel Pump Relay, to work with the XFI Fast. Here is what I am looking for.

I have a 1987 IROC-Z and I know the 3 wires from the fuel pump go into a connector that is mounted just behind the rear seat into the interior of the car. 1 wire is to feed the pump, 1 wire for the sending unit and 1 is ground. I have checked under both door sills and can't find the wires. Do they run in the center of the car towards the front under the center console.? I have found speaker wires under the passenger side of the car. And about 15 or so wires in the left side sill plate but these are all lighting, rear defrost, Seat Control and speakers. Any help would be greatly appreciated

 

They run down the middle of the car, under the center console.

 

my 86 didnt have a intank pump, so i dont know if its different, but all 3 wires are there, and the wires from the tank go across the floor but the rear seat lower cushion mounts, to the driverside door sill and to the front of the car.

 

do you have the carpet out? if you pull the seats in the back out and pull back the carpet on the floor, you will see the 3 wires in a piece of convoluted tubing running toward the front. The ground stops under the rear seats

 

Don't have the seats or carpet out as of yet. So I should be able to access these from the Center console shifter lever? Appreciate the help

 

the wires come into the car behind the rear seat backs, if you have split seats like my tta, they come in between the two rear seat backs

 

I found them. After they come in behind the carpet behind the seats, they change colors to Pink, Blue and Black. I guess they had a hard day at GM when mine was assembled. The ground wire did in fact ground directly under the rear seat behind the drivers seat. The remaining wires then went to the drivers door sill and towards the front of the car. I appreciate the help.
