Hack job on wiring?

Ive bought this car a while back.It ran perfect until I wanted to take the fan they installed on a switch to the back to the stock one. They cut into one of the relays near the brake booster.I do know they are the fuel pump relay and the fan relay.I think they cut into the fuel pump relay due to the fact that that car will only crank.I ran a wire from a the red wire off the fuel pump relay to the fuse box.I believe its the fuel pump one because you hear the pump and it starts.BUT NOW the car idles high, sputters and runs shitty.I want to have the pump have power but not by having the wire to the fuse box. I'm at a lose right now.What I to have done is to check to pump and wiring of the fuel pump.If you guys have a similar problem that you solved pleased help.

Re: Hack job on wiring?

OKay thanks for the wiring diagram.BUt now the fuel pump only works when I have a fusable wire going for the red wire to the fuse box(ING-Ignition Fuse).The idle has corrected itself.The only thing is now im getting a code 51, which i believe to a prom error because the SES light flashes quickly.The ECM is new has about a year on it and the car hasnt moved since May.I got a junkyard prom engine code E but still the same so I order a hyp-121361 chip /prom should be hear by friday.Also on a hard acceleration the acts as if it isnt getting enough fuel, but the pump is new as of last october and relay as of yesterday, filter changed and new ground so im still done for.Any thoughts?
