I have the aem V2 6100 for the supra TT in my car. Does anyone have this setup and working AC. I found some threads on wiring in a low voltage relay a while back, but I can not find them anymore. And now it is really HOT. Any help would be appreciated.

 

If this is the same as the aem that dm sells, pm me or search sc400 air conditioning not working 1jz, in the performance section. GL

 

Not sure, but my harness is different than the 1j. Does anyone know what signal is sent to the ecu when you hit the ac button? Ground, power, 12v, 5v?

 

AAron , I will be doing mine this weekend also , my A/C doesn't work and i even had Brad tryin to setup it but no luck.
My car is a 96 also , I thought you only need a relay stuff for the 2jzgte or 1jzgte ? Last time i check you just go in the settings and turn it ON atleast on my 95 SC i did.

 

v2 should work as stock . in other words ,we have a gte in a sc using v2 , and alpha activated a/c request within aem/protuner and its on .. protuner saw a/c and alpha has full control

 

Yeah, Brad went into the aem and we could see the AC trying to switch on in the aem. I have the supra TT unit and I think the ecu puts out a low voltage signal and our relay is activated by the factory ecu sending a ground to activate the relay. I don't have my supra wiring diagram at the moment so I only know half the puzzle.

 

AAron let me dig into it more this weekend hopefully , i'll have something for you.

Your car is 96 my car is 96 same tuner and you have V2 , i have V1 lol it's in the wiring!

 

Lol, I just checked the pressures. I have none. Evacking the system now. Should have ac in about 15 minutes. Should have checked that first.

 

bumppers!!!
