4.8L harness question??

I have a 4.8L out of a 2007 Silverado that I am swapping into my '93 240sx. My only problem is that I dont have the engine harness, and I have yet to find one.

I was just wondering if anyone had one for sell or knows where I can buy one. Or even have one made.

All help is appreciated.

Thanks,
Chase

There are several places that will custom make one for you, but they are expensive. I have an LS1 harness that I am planning to modify, but I don't know what all is different in the two. Maybe someone that knows the differences will post up.

^I was planning on converting to a throttle cable instead of using DBW.

If you have a 07 4.8, you can buy a older 99-05 (cable style tb) wiring harness, pcm, and tb. The engines are all the same.

Not so.I just bought a new style 07 4.8 and trans for my malibu wagon..took the TB off to go swap with a cable drive from an 02 and they aren't even the same,and will not bolt up.I'm not sure what to do short of exchanging intakes.
