I've purchased a CM3000 brain, and am mapping out wiring before I begin. I'd like a little clarification on the second ignition wiring, which my car has.
Ref:
1990-93 celica
CN2-pin3 (-)2nd ignition 200mA output
So in order to get a (+) output to my vehicles's 2nd ignition wire, I need to solder this wire to the pigtail on CN1, and then use that relay's blue wire to hook up to my 2nd ignition wire (B/O on vehicle ignition harness).
This is my understanding, please let me know if I'm on the right track. If I'm way off base, please be gentle!
