block heater cord mod

i found this plug while i was seaching for parts for my boat. i really like it and thought id share. its suppose to be used for hooking shore power to a boat. i just used a hole saw cut a hole in the bumper and mounted it there. cut the plug off yer block heater and wired it up. it keeps the cord from falling out and getting dragged or run over which i have done a couple times. plus it looks a lil neater then the cord hanging outa the grill. you can mout it about anywhere ya want. O and they cost about 20 bucks shipped, i'll try to find the website where i got it but they have them at most marinas and good boat shops.

Practically all emergency responder equipment has them, but one better. They have it self eject the cord when you turn the key on. A key on hot and a ground is all it takes to hook it up. For those real lazy people at home.

Not neccarily lazy in the late seventies the company I worked bought us 5.7 diesel chevys, These were hard to start in cool weather and one of my friends forgot to unplug his one morning and somehow the cord pulled his window frame out of his house.
I had to give him a hard time for awhile over that.

I did the same thing last year, except I put it on the drivers side. Why the hell should I have to walk all the way to the passenger side all the time? I added a piece of an extension cord to make it reach and zip tied it to the frame/bumper/whatever to keep it neat. It also allows you hook up one handed, much nicer when its cord and wet out, just push it in, or pull the cord to go.
I think the brand is marinco, I want to say I got mine off ebay, but it may have been a website. The only problem I've had, is the cover doesn't like to stay shut anymore. I think I'm going to try a bead of RTV around the cover to make it a touch thicker (let it harden before closing it).

Man I've been wanting to do that plug in the bumper thing for a couple years but couldn't find what I needed to make it work. Might have to look into that.

I do have one thing I think you should address on that install.

Is the back of the plug outside the frame?

If so I would put some kind of guard to keep ice off the cord and back of the plug.
Salt road spray will get inside and make short work of the wiring.
And that nice ice that forms in the wheel wells will also rip the wire out of the plug when it starts to warm up and big chunks of ice are breaking loose.

Last fall I completely rewired all the lights on my flatbed.
First snow storm I had not protected the wires from road spray, big ice chunks ripped both sides of the new wiring harness off.

I was more than slightly upset.

If you strip the outside back a bit you'll see the insulation of the three. Ground will be a different color, mine was green. The other two were the same.
