Hello. Looking for a brake-shifter interlock wire on a 2014 F150 limited (floor console). The end goal is to enable a switch and a person cannot put the vehicle in drive.

TIA

 

You probably didn't think this out...

What were you planning to do about the manual bypass procedure which would let anyone with interior access bypass the interlock?

 

Let me know the proper way to complete this.

I have a switch to keep power to power-run (pin 1) and power-accessory (pin 6) on the ignition connector. When I take the key out, it continues to run. There is no voltage on the "key in", but the F150 will still let you shift. It seems the answer is to cut power on the brake-shifter interlock.

 

Is something broken and you're trying to work around it or are you looking to modify a vehicle that is working as designed?

If something is broken, it seems to me the correct thing to do is to fix it properly.

 

When I am on a fire 1/4 mile from the F150 and need to leave it running, I don't want to leave the keys in it and someone just drive off. So, I have a switch that keeps it running. In other vehicles, the shifter won't engage without "key in" having 12v on it. There is not any voltage on that wire with the key out.

 

Would it be enough to lock the running truck with the keypad?
Why does it need to be running? For how long?
Another solution would be to engage remote start after you leave the vehicle. You can get 30 minutes from the factory remote start.

 

Nah, someone with ill intentions can easily break the windows and run off with it.

May be out on the fire for an hour+half, so that would not work. My radio only shows up to 20 minutes, unless Forscan can extend it to 30 minutes. That would work, just not twenty minutes.

A solution with a relay is what I am ultimately looking for.

 

Ah, that finally makes some sense... Intercept the blue-orange wire between the BCM and the shift interlock module. That wire should go HOT when the interlock is to be released.

BTW, don't law enforcement vehicles have a feature that allows for them to continue to run unattended while being undrivable until the LEO returns? I remember hearing about it but don't recall the details. If that can be implemented in your truck, it might be a solution.

 

secure idle, i dont think it became a thing until 2015 or so

 

Thank you for the confirmation.

Some vehicles do and some do not. Most of them you have to either hotwire it like above or use a system like SoundOff Blueprint. The department cannot afford that $1,200 piece of equipment. There is also a cheap version option to set off the siren when a vehicle warning light comes on.

The good thing about BluePrint is that you can configure it endlessly. Temperature alarm, no power to compressor, engine temp alarm, press brake and die without the key in... all kinds of stuff.
