Air conditioner signal integration

[RedHeartbeat]

Nope, was running a Sanden compressor so I just triggered it from the 93 signal wire to the clutch and it stayed on all the time, no cycling. The coils would freeze up from time to time and I'd have to turn the a/c off so the fan could thaw it out.

Red, don't you mean, you just had it triggered from the accumalator pressure switch wire, via the A/C request relay?

I don't have that switch anymore. I had a trinary switch installed in the high pressure side. The green wire that used to go to the accumulator switch now goes to the trinary switch and then to the clutch.

i know this is an old thread but im in the same boat right now. ive got the fans wired for low/high and pcm is tuned for it and im ready to get the lines fabbed up for the compressor but if there is no way to controll the fans/idle using a regular 12v signal instead of the class 2, then i might as well scrap this plan and just do something else... which will be uneccesarily expensive!!!

i know i can get the fans to kick on high bypassing the computer with a few wires and a diode if i have to. but im concerned about the idle. how bad is it when the compressor is engaged? does it want to stall out? has a solution been figured out yet?
