hey guys, i have a sound performance triple fuel pump which sp had wired up to my fcon. since i had recently removed my fcon in favor of a pro-efi, i am unsure how to wire these up so it will start on just the stock ecu. any insight would be great. i can also post up pics if need be.

 

what wires on the factory plug could i splice into?

 

Did you call sound performance as you want those pump running off the proefi just like they did the FCON. YOu do not want 3 or even 2 pumps running at all times. The proefi stages the fuel pumps which is what you want.

But otherwise, you just need some relays.

you run main power to the relay, use the stock fuel pump power wire to trigger the relay. when the relay is switched, the main power will feed the pumps.

just follow this but add the 3rd pump

 

^awesome thank you. heres my current layout that sound performance did. str8dum1, let me know if im going about this correctly please

all 3 pumps go to a relay as shown here


the wiring from the relays connect as follows: all 3 white wires connect to 1 pink wire which goes to the fcon.
1 black wire connects to yellow wire which goes to fcon
2 black wires connect to green wire which connects to fcon


the green, pink, and yellow wires then connect to the fcon


so i would imagine that the green, yellow, and pink wire would have to be connected to the stock relay if im not mistaken?
i can hook up 1 pump at a time as they each have a seperate power wire going to the battery.

 

bump for helpz

 

I would talk to the guys at SP before you screw something up. It's hard telling without being there to follow it and set it up like you want it.

Since they sell the triple pump, they sell the proEFI and they wired it together for the fcon that you have now removed i would say the best thing is ask how they would prefer it be set up.

 

+1, its easy to wire them in to just work, but you want them to get controlled by the ems. hard to give advice without actually being there

good luck
