Looking for a 12v supply for a radar detector. So far, I have the wire run down to the right side center console. I am hoping there may be something there I can feed from, possibly the rear seat 12v supply. The only cables I really see are the usb cable going to the center console and a big gray plug with about 40 wires going in and out.

Any chance of a pinout on that plug so I can maybe find a spare? Or is there a better place that I could splice into?

I don't have a Haynes/Chilton manual yet, haven't been able to find one for it yet, but I intend to get one.

 

There are no "spare" circuits in the truck.

Best option is to use an Add-A-Fuse in any of the 2 slots
F36, 37, 41, 42 ( these are all hot in start or run position )

Slots 32 or 38 ( these are accessory delay fuses )

Slots 43 or 44 ( both marked as unused in the 2012 EVTM ).

This way the Unit is only on when the truck is on.

If you want it on at any time, you can use the fuse slot for the power point

 

Thanks for the suggestion. I went that route and added it to the slot for rear seat heaters, which I do not have, but there was a fuse for regardless. Every single slot was occupied by a fuse so I chose to pick something that seemed non-critical.

The only problem I ran into was I was unable to put the fuse box cover back on. It is still covered by the kick panel so I think it will be ok???

Thank you.
