Help please with fuel pump relay wiring

[razorbak]

This is the ATI pump....there is a small diagram on the relay, but it doesn't correspond to the wires, and the install manual doesn't mention wire colors or have a diagram either...can anyone tell me what wire goes with what terminal?

Thanks! Al

Here's a link to Vortech's site, download the pdf file for the T-rex installation for your year model. It tells you what wires to tap into, you can always double check by using a test light as well.

Thanks for the reply....the problem isn't with my car though, it is with the ATI relay itself. There are four wires, black, orange, yellow, and green coming off the ATI supplied relay. The terminals are 30,85,86 and 87. There is nothing on the relay telling which terminal corresponds to which color of wire on the other end.

The numbering on the relays is the common markings, what may try is to do a search on "google" or the like for relay wiring or similiar terms. I had bought a used nitrous kit a while back and had to wire my own relay, this is what I did. One terminal is a ground, one is your 12v power source, another will be the 12v power that "activates" the relay (tie this one into your existing F/P wiring), can't recall what the fourth terminal is for though.
