A plain SPST (on-off) relay.
The input +12V power for the monitor to relay #30.
+12V power to the monitor from #87.
+12V from ACC to #86.
Ground to #85.
How can I wire a 12v relay to the ACC to turn off the monitor? I have the monitor hookup to the M4 yellow and black.
Because when I go in a store and I hit the override switch the monitor stays on…and sometimes I for get to turn it off when I get out of the car.
So like this
I will give it a try this weekend.
What I did was...run both ground the monitor and pin 85 to the M4 ground and pin 30 to the M4 yellow 12v. That way the pc still give clean power to the monitor and not the car power.
Thanks OldSpark for helping me out on that.....
