Racetronix Hotwire to PSI conversion harness

[SStavin]

I have a Racetronix hotwire kit that installed with my old swap and I'm mating it to the PSI conversion harness. I need to ID which wires on the Racetronix harness go where? Any help is appreciated!

I have 4 wires coming from the Racetronix harness:
Wire 1 Grey
Wire 2 Purple
Wire 3 Red (10 gauge fused originally running to the alternator)
Wire 4 Black

This is the Racetronix kit

Per instructions from PSI You can activate the Racetronix relay with the PSI fuel pump relay, that is computer controlled. Following the diagram, the wire in pos. 87 will be 12 volts when the PSI relay is active. Install that wire to the race tronix relay to the 12 activation signal.

I think the 2 relays would be redundant, and complicate things. Why not just use the PSI signal to trigger the Racetronix relay (which is the one you want to use, right?)?

While redundant PSI said keep everything in place. Not 100% sure this is right but, this is what I've come up with so far...

That's a CYA move.
I know you're trying, but I can't make sense of that mess. The easiest way to say it would be: wire whichever setup you want to use drive the pump, then wire the other system to trigger that (switched input).

Good point. As you originally pointed out; In order to simplify everything it sounds like the plan should be to eliminate the 'hotwire' kit. I think it would be best to have the computer driven relay control the pump. Does this look right?

Also, where is the best place to run switched power from for position 30 on the relay?
