Don't use the 5.3 a/c controls from the harness, just wire it into your factory harness. Do you really need the tow/haul switching? Disable it and run one standard setting. You shouldn't need all the BCM stuff from the donor truck. You should be able to disable all the unnecessary stuff and run the bare essentials by programming it out of the PCM. You can disable error codes that would be output to the SES light.
I find the comment about disabling it from the PCM interesting, I am going to be attempting to address this issue very soon as I am installing an LS1 in my '92 Typhoon.

Since I havent been exposed to the "NEWER" stuff that much I am not really all that familiar with what I would need inorder to 'talk' to the PCM, I realize some sort of software and a laptop but what is required on the TRUCK side of the equation?

Is the BCM required to make contact with the PCM ???
Other than a scrapyard, any idea where I can get a OBD-II plug ? (The Typhoon is not even OBD-I, it has an ALDL port)

I have a complete Engine, Harness and PCM from a wrecked '00 Camaro SS thats going in and I'd really like to know what I am going to need other than the harness and PCM to talk to the stock LS1 PCM...

Any additional information would be great. Sorry DOCGREEN9 not trying to hijack your thread or anything, it just seemed like a good time to chime in and ask..

Thanks in advance !
