I wanted to clean up the stock heater plug and add a rear plug at the same time.
Here is what I did...

Tools and supplies:

Here is the plug receptacle I used for the front

I got mine on E-bay for about $18

The rear plug was a 9-pin trailer plug hook up I had with a removable pin insert. I took out the insert a tossed it.
25' extension cord 14/3 gauge wire
Additional 20" piece of 14/3 power cord wire
Female cord end with ground

First I prepped the plug for the rear, removing the pin insert

Then cut the female end off the extension cord and insert the cut end into the front of the empty housing.
I soldered the ends of the cord wire to make a more solid connection with the replacement plug.

The housing has a screw down hold-fast for the cord so it doesn't move when plugging in or disconnecting.
Here is the view in the housing.

I had a spare trailer plug mounting bracket laying around to mount the rear plug to the bumper. I drilled and tapped the underside lip of the bumper and installed the whole assembly.

Now route the extension cord along the frame rail to the front of the truck. I decided to install the front plug on the drivers side in the air dam. I didn't want to cut my existing heater plug so I installed a short cord with a new female end on it. This will allow you to also tap in the cord from the rear as shown.

Secure everything with cable ties and get ready to drill your air dam. The Marinco plug uses a 1 7/8" hole.
I located mine under the driver side tow hook.

It gives a nice, clean, almost stock look to the heater plug and now it doesn't flop around and scratch my bumper any mor. Now I can plug in whether I pull in or back in

Forgot to mention, use an oxidation eliminating paste like OxiBan

to minimize corrosion

 

That's the first time I've ever seen a front AND rear outlet !! Is everything waterproof?

 

The front plug is one used on boats to allow on board battery charging and comes with a rubber type boot that seals the wire and a gasketed door. The rear is the same as the 7-pin on the back of your truck now with the guts removed. I put the molded male end in the rear housing to keep things weather tight.

Mayfair, I thought you installed a place in the back for your plug in a while back?

 

Pretty slick!!

 

Just one thought is if you live where they use road salt in the wintertime your power cord under the truck may have a short life span.

 

I put Oxi-Ban on the wires and plug to try to minimize that

 

Yeah, i did, and i threw a battery charger into the mix as well while doing it

 

Very cool. Definitely need to do this. Especially like the onboard charger.
