After dozens of search term combinations I've given up on trying to find my answer, feel free to find the correct ones and laugh at my sorry ***

Alright here goes, I've got a Carter Pump installed, has been for a long time, but I'm finally gettting around to replacing the stock power wire as it tends to oscillate with the turn signals and dip when electrical load is put on the system.

I've got some new 14g wire, but I cannot find the post where someone explained how to run that wire back to the fuse box. I'm pretty sure that someone said that running new wire back to the box should be sufficient to deliver constant power. I'd rather not run new wires straight to the battery. I am going to be using a fuel pump cut switch, but I'd prefer not to have to use it everytime, just when I don't like where I'm parked.

 

Here's the best and easiest way. Run the new positive cable straight from the battery (with a fuse of course) and use the stock fuel pump wiring to switch a relay. Works great.

 

Fair enough.

Now I came across that answer alot of times while searching about cut switches. Two things I don't fully understand, what type of relay would I use, and how does this solve the problem of poor stock wiring? What is the point in upgrading the wires only to re-use a section of the crappy wire? I guess I also don't understand where the new and old wiring would meet. Thanks for the quick reply though.

 

You can use a conventional 30A 4-pin relay.

The juice for the fuel pump will be coming straight from the battery through the new wire. You need the relay there so it only comes on when you turn the ignition on. The old wiring is only there to energize the relay.

 

I've been meaning to do this as well but I haven't been able to find a "conventional 30A 4-pin relay". You'd think this should be easy but the auto parts store guys keep trying to sell me "fog light" relays. I think they're 6-pin. Anyway, are there any places on-line where I can order this thing? It would be nice to get a relay with a connector and small wiring harness attached. TIA


EDIT - haha .... I just checked eBay. There are tons listed and some even have the harness.
