Ok, I got rid of all the factory wiring that i'm not using, Brake/fan relays/cam sensor/crank/oil/coilpack/AC wires etc.
Since this is a race application i wanted to clean up all the wiring, and i also saved a fair bit of weight while i was at it!
Anyways, i get power to the caspers box, (standby and 12v with key on) and the motor cranks but nothing for the xfi (all lights out).
I also have no fuel pump prime now, i have the xfi hotwired and am getting power to the relay.
I'm thinking a ground possibly, i removed the wires and pinout connector's for everything i was not using..
Ground issue for the xfi??
T.I.A.
 
You won't get fuel pump prime if the xfi isn't getting powered. This is where the led lights on the box are very helpful. I would check all grounds to include the Casper box and verify switched power on Pin B17 & battery power on pin B18. I realize it's too late now, but before I butchered up a stock harness, I would have tried selling it along with the adaptor box and then bought the FAST stand alone harness.
