I am using a ca18et ac compressor/ clutch on my ca18det, mainly so I didn't have open the system when I did my swap. The compressor is hooked up to the ca18et wiring harness, which I didn't need to remove with the swap. Basically all I did was unbolt the compressor from the ca18et, layed it to the side in the engine bay fully charged, pulled ca18et, installed ca18det, then bolted it back up.Problem I have is when I turn on the switch inside, the clutch engages/ disengages like every 1 sec......almost like there is a short somewhere. It worked fine on my ca18et before the swap.Do I need to wire in the compressor somehow to the ca18det harness? Does the ecu control the ac or something....or is my problem somewhere else?Thanks for any help

I know for S13 the green and yellow wire is for the AC relay. not sure about s12s



maybe re-reading this might help?

Thanks for that link......I think I figured it out.......the S12 pulley is a v belt pulley......and I tried to use a 3 rib serpentine belt on it to match the tensioner, and crank pulley. Thought it would work. When I first cranked up the car everything was fine.....as I turned on the ac and let it idle, the clutch engaged and worked for about 15 secs, then I heard a thunk sound, and thats when the clutch started engaging, and disengaging every 1 sec or so. Upon closer inspection today, the belt had turned itself part way inside out.....with a 2-3 inch gash in the center of it. I just ended up cutting the belt off. For kicks after I cut the belt off, I cranked it back up, and turned on the ac......the clutch engaged, and stayed engaged......so I think my problem was the belt was about to self destruct.I have a z31 serpentine pulley that fits the ca18et compressor, but it's offset from the tensioner, and crank pulley. Maybe the skinny 3 rib belt will allow it to work......I know the fatter ac belt won't. Anyway, back to square 1
