Well, I ordered and received the relays. I want to mod the front AC before trying to figure out the dual rear unit. My front unit is a single compressor and the control pcb is half the size of the dual unit. I'm still studying the drawing and have a couple of questions. It looks like the fans still receive ac from the circuit board. And, it looks like 120 VAC input is still connected and the 120VAC that used to feed the compressor now feeds the external relays. So, the relays on the pcb still need to work to turn on the external relays. Am I getting this right?
