AC compressor control, idle control with AC, compressor over-rev protection, cooling fan control based on both coolant temp and AC function.....all done by the C5 engine ECU and can not be done on LS3 and LS7 ECU's. That little reluctor wheel adapter just might be the easiest solution to all of that?....nice find!
Hi Shane,
Are you saying it does not even have the fan relay output? my older ls376 at least had that, but no AC control, that would be trouble.
