--------------------------------------------------------------------------------

I've got an 88 lx that I've converted over to a carb set up. I sold all the fuel injection stuff, but I do have an old speed density engine harness laying here. Im trying to get the a\c to work on the car, but trying to sort out the mess of wires is a nightmare. Especially since it all runs through the computer. Anyway, does anyone know what I need to do to get the a\c system to work without the computer. I dont need things like the WOT relay but they are all wired together and all go to the computer harness. Im usually not to bad with minor wireing and such, but I dont know much about wiring up and a\c system.

Thanks
