I did an LS swap on my car about 4 years ago and removed the original computer and it’s harness just like you did. My hvac blower still works except for the high speed. That 4 position connector near the accumulator was getting power from a cable on the starter for the high speed. Is your ac fully functional?

I’m putting my olds cutlass supreme together. Trying to figure out what to do with that harness. So u just delete the ecm and harness? What about the trans plug?

You need a lockup module. I used the Bowler kit

when you removed the computer did you have any trouble with the cruise control in outher words does it have any affect on cc

I've been planning an update with this information here in the coming few weeks. Taken straight from www.montecarloss.com, here is the information from a sticky thread:
Find your buffer box, it is a small green box located behind the stereo(drivers side) there is a total of 7 wires coming out of it. Three are together coming out of the bottom (RED, GREEN, BLACK) these wires run to the VSS on the back of the speedo, GREEN is 12V, BLACK is Ground, and RED is the SIGNAL to the BUFFER.
Next you will find two harnesses on the top off the buffer box, one SINGLE YELLOW wire, this sends the signal to the Cruise Control Module, also there is a 3 wire harness, this is where the BIG PROBLEM lies, PINK/W BLACK STRIPE wire is your 12V to power the VSS, BLACK/W WHITE STRIPE this is the GROUND, THIS WIRE USED TO GROUND TO THE COMPUTER HARNESS, THAT IS WHY YOUR CRUISE WONT WORK!!! CUT THIS WIRE AND GROUND IT WITH YOUR STEREO HARNESS. NOW YOUR CRUISE SHOULD WORK. Also has a brown wire, this can be ignored, it is the VSS signal to the computer.

Have you tested the a/c yet? Thanks

I won't have the car running until spring, but I got this information from several people who've successfully done this just as I described. I also have the electrical diagrams that confirm this. Once the car is running, I'll update this video. I wanted to show what needed done before anything was cut or removed.
