Re: AC compressor relay and Trinary switch wiring question
That looks like it should work. The only thing I'm not positive about is the back feeding 12v to the AC request wire as I have never hooked one up that way, but I have heard it may bump the idle a bit, but again I have no first hand knowledge of it.

Do this, you don't need a trinary switch. Trigger the fan relay off of the compressor relay. Ignore PCM pins 33 and 11. [IMG]  [/IMG]Photo courtesy of lt1swap.com Last edited by Davidf; 10-14-2021 at 02:17 PM. |
