hello

i`m bussy with the swap from tpi to carb!
i have strip out the tpi harness ,so i only have left some wires that i need!

i have read these thread/post and don`t understand it about the fuel wiring relay!
i have a 1988 iroc-z 5,7 v8 and my wires of the fuel relay are different
and i have no 3 wire oil sending unit but it`s a 2 wire!

there are some letters on the fuel plug

A: Tan/white (that go`s from the plug to the oil pressure sending plug)
B:Black/white ??
C:Green/white ??
D:Orange (smal wire that go into the C100 plug)
E:Orange (big wire that go from the plug to the oil pressure sending plug)

so is here anyone who can tell me what to do for working the intank fuel pump

I added a 12v (while key is on) source to the green/white wire going to the fuel pump relay beside the brake booster.

 

and then it will run? when ignition goes on?

so it`s never hat to do with the oil presure sending unit?
