Hi,

I'm putting this in my 3rd gen and was wondering if anyone has a link to a thread where this was done or a wiring diagram.

I want to trigger the hotwire withy Terminator x fuel pump wire.

Thanks

I can Post an Image of the Holley EFI Terminator X Wiring Diagram...
Which Engine/ Ignition System are you using (58X, Etc...)?

Leon82

It's is a 24x 1x lq4. With the tbss intake DBC.

Thanks

First, here is the Entire Wiring Diagram...
I'll crop part of it next, regarding the "Built-In" Low Amperage (10A) Fuel Pump Circuit.

Actually...

Are you using the Relay from the Racetronix Wiring, or the Relay in the Holley Wiring?

Leon82

I haven't decided yet. I figured I would use the racetronix, triggered by the Holley, because it has the heavy power wire. But I know I could just use the Holley wire. I used to have a sniper so wiring it for just the Holley won't be a problem.

Okay, so all you need then is to apply 12 Volts Positive to the Red Wire at Pin A2 of the Larger Electrical Connector (34-Way) of the Holley EFI PCM.
That will trigger the Relay in the Holley Wiring to Power Your Racetronix Fuel Pump.

The Green 14AWG Wire from the Relay (in the Holley Wiring) is the Power Wire (12 Volts Positive) to connect to your Fuel Pump.

The racetronix kit plugs into stock body line at the tank side and uses the stock fuel pump relay as the trigger

all you have to do is run the holley fuel pump wire to the i believe green wire on the stock fuel pump relay.

LOL, so there are 3 different Relays in question of use...

It is up to the OP to decide what they wish to use, or not use.

Thanks for sharing that diagram @vorteciroc , don't believe I've seen that one before and it has wire gauges on it which also isn't seen often.

vorteciroc

Most Welcome!


That Image is from the Schematics Section of the Holley EFI (Dominator, HP, Terminator, Etc) Instruction Manual.

You guys should all have Copies by now:

I guess i should clarify if you had a efi factory equipped car and still have the wiring. I think the tpi and tbi used similar relays. Stock tpi had a fuel pump wire goin to it to control the pump. Thats the wire you send to the holleys fuel pump output wire

Thanks, I will look at the harness and factory connector closer. It is currently a TBI car
