Plastic Knock Out - Rear Bumper

[Msw1382]

Does anyone know what the plastic knock-out is for on the rear bumper to the left of the license plate? I'm considering making that hole larger to mount a plug that I'll have attached to a cable for the block heater.

That’s a long way to run a cable for a block heater?

I’d be interested to see that setup.

No different than an extension cord.

I've lots of length between my house panel and where I plug in my block heater and charger cords.

No, I get that.

I’m just saying that taking the time to run the required wiring along the frame up to the block seems like a lot of work for something that can be accomplished with an extension cord on the ground (that you’ve already got out anyways).

I almost always back into my driveway(s) and pretty much every time I park. My thought is if you forget to unplug the connection it will unplug itself with minimal to no damage.

I always have to loop the cord over my drivers side mirror, or else I will forget to unplug it with absolute certainty, so I get that.

I can count on one two hands, the number of times I've forgotten to unplug a cord.

This is exactly why I’m doing this lol. I’ll take some pics when I get it all routed

Take a look at installing a Noco plug port in that knockout. It you ever drive away, the cord end will pull straight out, no damage.

Yup. That’s what I have ready. Just waiting for the temp to be above 10….

If you’ve never had one where you forgot to unplug, backed out, and the plug decided to stick (because you were stupid enough to use an extension cord with a locking plug), then recoil back like a spring and take out half the plastic of your front grill in -2°F weather…..

You’re clearly not trying hard enough.

It’s never happened to me either, I was just thinking up a hypothetical scenario.

Our ambulances were equipped with a receptacle that kicked out the cord as soon as the truck started.

Kussmaul Auto-Eject plugs
They’re pretty cool. Can use them to provide shore power, charge batteries, etc etc.
We had them on all of our trucks as well. They powered our onboard mini fridges full of bottle water and charged all of our cordless tool batters, portable radios, etc. They disconnect and eject automatically on engine start up. When we pulled on scene and fired the onboard generators up, those would takeover electrical duty until we got back to the station. Very very handy. Not sure we ever had ours wired to run block heaters though. The station was always heated.
