So I've been running on my LT8s for a few weeks now and just noticed the other day that my A/C doesn't turn on anymore. A quick glance at the wiring schematics for the car show a couple of wires for the A/C going to the ECU. That explains why it's no longer working. ;-) Now, can anyone give me some tips on how to wire it up so I can get my A/C back without the stock ECU being in the car? Thanks.

Did a search and answered my own question. ;-) https://www.rx7club.com/showthread.p...light=a%2Fc%2A And the A/C will still cycle the compressor on and off too avoid freezing up the system.

That is the same thread I used and my A/C works fine. Idle was more of a challlenge with the A/C at full blast.

 

OK, I read this other thread and their seems like 2 ans 1/2 answers in it. Someone that has it working right, can you clarify?
1) Add +12v to the blue/white and blue/orange wires?
2) Just run together the blue/white and blue/orange wires?
or
2 and 1/2) Tie the same two wires together and tap into the realay of the E-fan?

I just want to be sure I do this right the first time!
Thanks...
Also, how is idle with A/C blowing? I don't plan to use it except when it rains!

 

Good point^ was confused myself?

 

I don't have an E-fan, so I used the other method. Idle is at 1200 rpm. With the A/C full blast it idles at 800 rpm.
