I have my positive wire of my inline electric fuel pump wired to a toggle switch. Wanted to rewire to something else. Is there any power source within the engine bay that i can connect to?

 

it needs to be wired to a relay, easiest thing to do is wire it to the pump output of the stock relay. since you didnt say what car you have, you can look on austin third gen for your yr/model/engine diagram and that will tell you what wire to use.

 

Thnx jw. Likewise its a 92 tbi conv to carb. Where is the stock relay and what color wire should i tap into?

 

on my 87 it was behind the brake booster area. it says its a gray wire. do you still have the pcm hooked up? if not hook up the dk green/white trace wire to a key on 12v
