Thread: Aux Power for 12 Pin Trailer Plug

I need to install a flat 12 pin trailer plug in place of the round 7 pin.
The number 12 pin needs an auxilary 12v power (ignition on) to trigger the trailer charging system.

Is there a convenient 12v power supply in the rear area that is powered when the ignition is on that I can tap into?

thanks again for any advise

The cargo area cigaret socket can be taped to give you an IGNITION ON signal

BUT, if the WHITE ( S12 ) plug is still in place, there is a FRIDGE circuit that is only on while the motor is RUNNING.
