Ignition interlock keep it running button

Ok, ive spent days trying to find information on what i want w no luck.

All my cop cars have a button i can press, turn the key off, remove the key, and the car stays running.

I want this on my truck, i leave it running when going into convenience stores and so on, im always worried some crackhead will jump in my truck and take off with it. How can i wire something like this into my truck?

What's your truck?

How is that function handled when you return to the cop car? That is, do you have to hit the switch again or does the function autocratically reset when the key is re-inserted and turned back to RUN?

once you return to the car you have to reinsert the key in order to put it in gear and unlock the steering wheel. The button is just that, a push button that pops back out once you remove your finger, its not like a toggle.

However whatever relay or thing that button engages, does not turn off until the car goes back into gear.

Meaning once you hit the button you can turn the key on and off and remove the key an infinite amount of times and the car will remain running. However if you put the key in, turn it on ,and put it into gear and then put it back into park and turn the key off then it will shut the car off.

Put a third party remote start in. To do what you want, push the fob when you park and take your keys with you. As soon as someone touches the brake to shift, the engine shuts off (unless the key is in and in the "on" position).

I thought about doing something like this years ago, but never got around to it.

What you can do is wire the brake pedal release switch, the switch that released the lock so you can put it in gear to a hidden switch, or upfitter switch.

With the switch flipped, the brake release is dead and you cannot shift from park. Flip the switch and it works like normal again. Or vice versa...

Then just leave it running, lock the doors with the keypad. If they break in, they at least wont be able to shift it out of park and run off with your truck.

Im not sure thats what i want to do, i dont want a remote start on my diesel. Im sure its a matter of wiring in some kind of relay into the ignition system, i just dont know how or where to do it.

Sorry. I thought those were standard issue on the SDs. My mistake.

Have you googled police car equipment places to see what they may offer?

EDIT - You could just carry a loose door key in your pocket and do the brake lock switch trick?

found it, everything i googled brought up this thing called Run Lock but its for the UK..... Finally i figured out what its called in the states Secure Idle, now i know which direction to go. I think its a great addition to put on a diesel, i hate shuttin my truck off just to run in a store for 10 minutes, but i hate leaving it running and unlocked.

And in places like Tacoma WA you get a nice ticket for
a vehicle idling while unattended.

The reason is not for smog. It do to the high number of
cars that have been left in the driveway that some crackhead
has jumped into and run off with it.

With the remote start, you can't drive the car without the key; can just run the engine. Even if you open the hood when the remote start is active, it will kill the engine.

Cannot happen with a properly installed runlock system. The steering wheel will be locked, plus, when the brake (or clutch, if a manual) pedal is pressed, the runlock automatically disengages and defaults back to the ignition switch state. If the key is inserted and the switch is in the RUN position, that's what it will continue to do. If the switch is in the OFF position, the ignition system's power will be removed, the engine will die, and it can only be restarted with the key.

Probably wouldn't be too hard to whip up a simple circuit with a couple of relays and some logic for a basic DIY unit.

Edit: Okay, did a bit of poking around. Basic circuit is as follows:

Dual coil latching relay as the switching "controller". The "on" coil is connected to a momentary contact switch that is connected to the "HOT IN RUN" circuit. The "off" coil is connected to the brake light circuit. Load relay(s) would connect via fuse to ALWAYS HOT vehicle power via relay's COMMON to relay NO terminals when energized. Connect the NO contact of relay(s) to each of the circuits from the ignition switch that is supposed to be HOT IN RUN (START/ACCY). On the OP's truck, there are four circuits that should be switched to duplicate the ignition switch function. That would be 1 x 4PST, 2 x DPST, or 4 x SPST load relays, for example.

You could probably do the whole thing with a single 4PDT/4PST dual coil latching relay if you can find one with contacts rated at high enough current. I found a Magnecraft 755XBXCD-12D or 785XBXCD-12D relay (around $20) that is rated at up to 16A on the contacts, but I'd suspect a much higher rating would be more appropriate.

There are surely many ways to do this, this is just the one I came up with this morning over a cup of coffee.
