LT1 wiring assistance needed please...
In the process of wiring my LT1, no fuel pump, and no crank. I read awhile back i need to modify the starter relay, by grounding a wire on the relay? anyone familiar? I cant seem to find that info again, And what all has to splice into the c207 under the dash to get the car running? BTW: i have the ALDL spliced in and mounted under the hood already from the blue connector) I know for sure the check engine light, and also i need to bypass the vats, but i dont know what resistor i need, nor do i have access to the car or the bcm for this engine, just the ecm and harness. I have the underhood fuse box wired into my fans, and fuel injectors (via plug c100 on lt1 harness) most everything else is stripped out, and i do have power at the box and to the rest of the car and fuses and lights and stuff work. Currently i have nothing hooked up at c207 and the pinouts don't speak my same language apparently, lol. also, i am using the 3rd gen fuel pump relay, its all hooked up to the pump and LT1 harness, but where does the red wire go on the relay? maybe that's a dumb question? is there something i need to eliminate to get the pump to run? i have followed pockets threads on stripping the 3rd gen harness and i had also stripped out pretty much everything but fans, ac, and the injector wiring from the underhood LT1 harness and hooked up the batt/keyed hot/grounds. any help appreciated, i know there not that many people doing the lt swaps with the new ls stuff but im on a budget...
