T4topher I think I have it figured out. Thank you for the reply. I found this online "Yea you don't need to add a relay to activate a relay. The twin compressor has all relays built into unit and actually they are wired as separate circuits on load power side. Just take your relay activation wire and run them to your Toyota factory switch".
I then went to a local shop and had them look at the set up and they said that I have it correctly installed and do not need a relay for the twin compressor.
I am hoping this is all correct, so for now it's what I'm going with.
I am not sure if the single compressor had a different relay set up and required one to be wired in or not? I found way more info for wiring in a single compressor with a relay rather than a twin. Either way I have learned a lot more about wiring and relays than I knew before, so I appreciate that.
