Dual pump wiring
Im trying to make sure I wire up my fuel system right. I am relocating my battery to the back of the car also. Im guessing i just need to connect the pumps to power and ground, but the relay has me confused. Like I said, i want to wired this up correctly. Here are some pics of what I have. Any help on how to wire this up would be appreciated:

Re: Dual pump wiring
You just have a single fuel feed line right? So both pumps feed the same thing.
Don't know why you need two relays there. You can wire them seperately one for each pump but seems to me like it would make more sense to just use one relay.
Running larger wire, comes straight off your battery. Run that into the white terminal of the relay and the other side to the pumps.
Run the stock signal line to the blue and the other side to ground.

Re: Dual pump wiring
There is two ways i can help you here... you can either photoshop with writing what the terminals on the relays are numbered.... because its not a standard 5 prong. So id be guessing on triggers (which i can prolly still get) or you can just say 12 3 6 9 oclock using the pic above.. and give me the numbers.
Using the two relays is better than running both on the 1 relay. You wouldnt want to over load the relay, but they will actually run off the 1 and prolly without problem. But the safer bet is the do the extra little bit of wiring.

Re: Dual pump wiring
It looks like the relays are color coordinated. White to white and blue to blue. Also looks like they accept different gauge wires. White is going to be the larger of the two making it the upgraded power wire. Blue smaller being the signal from ecu.

Re: Dual pump wiring
why do you need two pumps btw?
i have one relay running both my pumps.. stock pump power is the switch to connect alternator power straight to both pumps.. grounds to ground(a new better ground)

Re: Dual pump wiring
id you didnt get a schematic with the relays you can find it online i'm sure..somewhere, or even on the back of a relay at radio shack.
hope you didnt get ripped too bad on that dual pump kit
