Ignition Wiring Error I am hoping someone can help.
I have a 2002 LS1 that I am using in a project car. I am using the exsisting wiring loom and ECU. In my ignorance and stupidity
while thinning the loom out of unwanted wiring I now have no 12v supply to the Coil Pack Subharness Connector Pin H, Pink Wire. and subsequently no spark
The wire leaves this plug and teminates at a common connector nearby.
Where does this wire continue too. Does it go to a pin on the ecu or is it a switched live on the ignition or maybe something else.
I hope I have explained myself well enough. Please ask if you need more info
Thanks Alan

The same wire that powers your coils also will power the injectors. One pink wire will power the even numbers and another will power the odd numbers. If you have power at the pink wire to the injectors, you can tap into those wires for the coils.

Many thanks for the replies. Unfortunetly all the pink wires, including the injectors terminate together on each side near each coil pack multi connector. I have obviously foolishly stripped out the feed wires that come from somewhere like the ecu or ignition, just not sure where this feed comes from.

The pink wires should only be hot in run and start. Each side should have a separate 15amp fuse. Do NOT tie both even and odds together. Depending on the vehicle your swapping into, you might consider using a relay between fuses and battery, unless your tapping directly into one of the RUN/START primary's directly from the key.
Send me a PM if you like and I can pull the wire diagrams from both vehicles and create a cross reference for you.
