sorry i messed somthing up.... My fuel pump keeps shutting off at random times... My firend re-wired the fuel pump ( moved relay to back, ran new wire from battery to pump etc.) There 2 black stock wires that keep turing my relay off for the fuel pump. It goes into a big wrie harness that looks like it goes to the front? Does anyone know where theses 2 wires go? or has anyone had this problem before?

those are the stock power and ground wires for the fuel pump. I use them as power and ground on my relay as well.

if the stock fuel pump power wire is losing power. I would re check the lines at the front where you cut away the relay resister from.

also keep in mind. that line will not have power unless the car is running or cranking.

or if the key is on and if the fuel pump jumper is jumpered (under the hood)

incase you are trying to test it with only having the key on.
