Hi Guys, new to the forum. I am in the process of planning an LS1 swap. I have the 0411 PCM conversion in place. I think I have the engine mounts, trans adapter, exhaust, sump, fuel system and injection wiring under control. Can someone help me with the ignition wiring? I have read about 10 wires to be run. Is there any others? Would just like to confirm what I think has to happen. I`m sure it is written somewhere but after weeks of searching I`m hoping someone can inform or guide me to this info or anything I have missed. Cheers

Wiring info email lextech
He can send you the file for people who already 0411 swapped outlining the wires and where they come from

Hi, thanks for the reply. How do I find Lextech? I was in contact with him some time ago for the awesome 0411 conversion on gmtruckcentral but that forum seems to have died. Is he on here? Cheers.

He doesn't seem to be on here at all lately. You might have better luck getting in touch with him via LS1Truck.com.

I posted a similar question on ls1truck and the only reply was that it had as much life as a cemetery. Should I pm him over there?

Worth a try I'd say.

It's a really easy wiring job. What ls1 donor vehicle harness are you going to be using?

OK, 34 pages may take a while to read through.

AS for the harness, I thought the plan was to modify the original. Is that not how it is done?
The engine and harness are from an aussie commodore and is drive by wire, I have fitted a cable operated throttle body and was not planning to use the LS1 harness.

What operating system do I need to load into the 0411? I have a copy of 12225074 which is a aussie commodore cable throttle body. Is there a better option?

I am feeling more confident with the other aspects of the project except for the wiring.

Cheers.
