I can't be alone in my wish to have rear outlet to only have power only with ignition on. We take a portable 12V cooler with us on the long trips, and it is a pain to run out to the trunk to turn it off at the gas station. Small battery can't sustain that power draw for long, so I do it every time.
The front in-dash outlet has switched power, and here's my attempt to provide that to the rear outlet.
Here's what I used:
- ATT- type add-a-circuit tap
- ATM- type fuse extension. I couldn't find ATT-type extension, but ATM will do no problem.
Cut off ATM prong portion:
Then solder add-a-circuit tap's external wire to one of the wires from the prong. You're not going to connect the other wire to anything, insulate it and leave alone:
Here's how mine looks like after wrapping it. Insert two 15A or 15 and 10A fuses in the tap.
At the car, inside the cabin, open the fuse box cover by your left foot. Here's what you're looking at and for. 15A fuses, the upper is for the front outlet, the lower- for rear. Power is provided to the outer prong of each fuse- right prong for the upper, left prong for the rear.
Take out both fuses. Insert your contraption in there the following way:
Add-a-circuit goes to the upper fuse slot. The wire should be facing left. ATM prong goes into the lower fuse slot. The prong that is connected to the tap wire should be on the right side. The way that the taps are inserted is VERY important:
Now check both outlets for the power while ignition is off and on. Open a cold one and congratulate yourself!
Do not try to run full load on both outlets at the same time. The circuit is protected by 30A fuse upstream, with many more loads on it.
