LS3 & Vintage Air Wiring
I'm hoping this is as simple as I think but then again I'm no electrician so here I am asking for help once again. We all know an LS3 comes with a black box that powers the LS3, it connects to the wiring harness and it has two wires coming from it, one for the fuel pump the other for the rad fan. I've also attached the vintage air wiring diagram when using a trinary switch. My understanding of this switch is when the rad fan is off(no engine coiling required), the switch will power up the rad fan when the AC system requires it. Do I just connect the blue wire (rad fan) from the LS3 power center to the 40A circuit breaker??
Thanks in advance,
Perry
