I switched over the infinity 8h back in January and last week I went to turn on my A/C and nothing. After testing all the fuses and relays I tried to tap on the compressor while the car was running but still nothing. I then ran a 12v wire to the compressor and the compressor turned on. After that I knew the infinity was not turning on the A/C. I started to read up about infinity and come to find out the 8h dose not support A/C. Is anyone running 8h with working A/C; how did you wire it up?


Thanks

Do you have an open lowside or highside output?

Also call aem they are very good over the phone, you can also post to the aem forums they normally respond in 1-24 hours. Most of my questions get answered within 2-3 hours, they are in California.

Thanks for the help, I will have to check but I think I have a highside open.

When running the smaller Infinity boxes on Evo's you have to use the Infinity-6 if you want to retain A/C. This is because LS6 (Pin 20 / AC Compressor Clutch Relay) is assigned to Injector7 as an available injector output.

You also lose the CEL light and Clutch switch on the 8h box. More details can be found at the top of page 6 of the below PDF:

Thank you for the info.
