ulitamate ls 7002 what does a/c integration wire do on ultimate ls system
don't know if this wire is suppose to have 12v on it and will it turn on a/c fans trough fan 2 wire
I would assume it gets a 12v signal from compressor clutch. Haven't used mine on my 600pa. Anything in the diagrams?
ya that's what I think too,i think it idle engine up when a/c is on don't know about turning a/c fans on
what im trying to find outif 12v is put on this wire to pcm ,pcm then pcm makes ground on fan wire 2
The fan 2 wire is for grounding the fan relay. The same as fan 1. If you have only one fan, I don't see any reas9n why you couldn't have fan 1 and fan 2 going to the same relay.
The a/c feature is desinged to raise idle and switch fan on. Still not sure what it is looking for as a signal. I would assume 12v from a/c clutch, but need to confirm that.
Have you tried calling Fitech?
Yes the a/c wire does get 12v from the compressor to turn on the fans and raise the idle.
