    I don't see why one couldn't devise an automatic plug-in arrangement so you could just drive up and have a car-mounted probe plug into a female connector of some kind, a la the aerial refueling systems used by the military. It'd be a dandy project.

    Because, the 120V AC power would be live on those pins as soon as the cord were plugged in.
    Try placing your tongue across the live pins to experience the safety issue. :eek:

    The prongs are on the car side of the connection. But yeah, this wouldn't fly.

    I run my extension cord from a timer, loop it around the leg of a barbecue we have parked at the head of the parking bay, and then about 4~5', to reach the plug-in at front lower grill. That cord is double zip-tied to a lower grill slat, with an inch or two between. In the event I forget to disconnect (happens once or twice per year) the connection pulls straight out, and it's easy enough that nothing gets stretched, ends up dragging on the ground.

    The prong side is the male connector. I was responding to @mfa-prius about why having the female end there is an unsafe, likely illegal, idea.

    Well, duh! That's the whole point. But place a timer and fuses ahead of the probe receptacle (I'll call it the "basket"), so that it would be live only during the time you wanted heat, and place a safety switch and the contactors inside the basket, so that it would be hard to get your tongue in there in the first place, and it would be plenty safe. I'm actually pretty far along with the design, and might have a prototype working in a week or so. Another reason to buy my 3D printer :). And having the probe visible at the front of the car would be way cool, although the biggest design issue right now is protecting the probe from damage during normal driving..

    Any better if you back in to park? A connector at the rear of the vehicle might be more out of the way.

    The male end of the block heater I installed years ago, had a cap on the end to protect the prongs.

    This new improved model did also, but the cap doesn't fit over the plug. In my design, the original plug would be plugged into a cord connecting to the probe; only the probe would be exposed.

    Good idea, but my garage is tricky to get into, and I'm more comfortable heading in. Right now, I've got my eye on a circular disk in the L side of the bumper that looks removable. No idea what it is, though, but it'd be a good spot for the probe. I'd like to make the probe retractable, but first things first.

    Mine did too, till I ground it, and half the plug off, on the road one time. :oops:

    A heads up for you gentlemen with big hands. I tried to install the block heater from underneath but "no joy". I would suggest if you have big hands like me it was far easier to install from the top, yes it took about 25 minutes to get the wiper cowl off. But you have so much more room to work with and you can see a tiny little sliver of your work environment rather than pure feel.

    Also cover the exhaust tin with electrical tape as it will cut the ^&*% out of you.

    ****TIP*** I loosely added a zip tie to the block heater as a handle and slide it off the end after the install. Good Luck

    I bought the block heater when my 2008 was new and tried installing it from underneath and failed. I had the car for ten years and never tried installing it again and gave it away this summer brand new.
    Maybe if the car was on a lift it would help.
