Hi guys, i have completed a ls1 swap in my shop, and i cant seem to find all the pink wires, i found 1 pink in the Blue connector 19, i also found the two orange wires that battery,

to my understanding there are more pink ignition wires but i cant find them in the red or blue pcm connectors....

should there be 3 wires that go to ignition? so far i have only found one.

Ok I'll play, PCM - 2 pink; MAF - 1 pink; TRANS - 1; COILS - 2; INJECTORS - 8; O2 SENSORS 1 EACH. They are in the harness, not going to the pcm.

Here is the schematic for the power wires from the pcm on a 99-02 f-body. will that answer your questions?

i still cant find them... in the other swaps i usually find all the wires in the bottom part of the fuse box (under fuse box), this wiring has no Fuse box wiring attached to it, or at least i cant seem to find it.

do i need to give power through the fuse box still? or directly from all sensors?

ok, so i opened up all the wiring and found the pinks!, but also the found Red and Green wires for the coils, should i also put these in ignition?

get yourself a good schematic. I got mine from LT1swap.com

These are the only wires that need power with ignition for the engine to run. ALL orange wires get 12V at all times. The only other wire you have to worry about is the starter signal wire. Other then that, that's it.

What did the harness come out of? Truck or car?

starter signal? maybe thats what im missing.... info on that... the wiring came out of an ls1 based car, which one i have no clue, also all sensors, coils and injectors are HOT, so when i run a test light everything has a current, but nothing wants to work..

The starter signal wire just activates the starter to engage. You should only have 2 wires to the starter. 1 signal, and 1 power wire straight off battery.

Your signal wire has to be hot in run AND start.
