Hey guys,

I would like to install a fuel pump cutoff switch since our trucks seem to be easily stolen with key scanners and are in high demand. I had this on numerous vehicles on the past. If you can't start it you ain't gonna get real far unless you have a towing. Anyways does anyone know the location and have the wiring diagram perhaps?? Thanks
Becareful doing this, the wire can get really hot or it can burn up the wire to the switch, they have very high voltage going thru them. Do the starter shutoff switch OR put a switch for 'Push Start Button'. I personally wouldn't recommend doing fuel pump switch, it might throw you some codes as well if you by mistake go to start the car and the fuel pump is not working.

I can 1000% confirm this. I just tried it in my Trackhawk.

You can put DPST/DPDT swtich on the RED wire on the Start/Stop button.

I just removed the RED wire from the plug and tried to start it, it won't start. I tried to start it (doesn't start), it locks the car and unlocks the car, alarm doesn't go off when you lock/unlock, and NO CODES whatsoever when I reconnected the RED wire and started the car.

Furthermore, I tried to remote start the car, it starts, BUT, once you put your foot on the brake pedal, it automatically shuts off, because that constant is not there.

I can 100% safely say you can use Start/Stop button to put a switch on it. Again, be careful this is constant 12v, make sure battery is off before doing any work with it.

If you're still have any doubts at all, unplug RED wired from that plug and try it yourself, but make sure nothing touches that RED wire, I can't stress this enough.

I wasn't sure if Zar_Trackhawk actually installed a switch or just temporarily pulled the red wire from the plug harness to test the idea. Regardless, it would be nice to hear some feedback or other ideas. I've looked into the Ravelco, but I would rather just have a hidden switch I can quickly flip.

I'm hopefully taking delivery of my '21 next week and I work in Chicago. Theft and car jackings are a significant daily concern. Plus, even in the 'burbs, a Hellcat was just stolen last week right off the dealer lot a few miles from me.
I actually installed it. I use it every time I go out. Installed it since I first posted it, haven't had any issues at all. No codes, no nothing, just like I tested it. 1000% works, but still do it at your own risk.

My problem was not with the electrical connection portion of the instal. My issue is that the guy did not mount the receptacle where I asked him to and instead put two screw holes through the leather panel that I explicitly told him not to. On top of that, he scratched up my custom billet fuse box cover. Keep in mind that I was just inside my office, he had my number AND I told him if he had any questions that he could call me and I’d be right out to answer them. He took it upon himself to install it exactly where I told him not to. He refunded the purchase price but is so far refusing to pay for the total damages. I contacted Ravelco headquarters and they said they don’t have anything to do with their installers as they are franchisees and do not offer any protection against the damage their installers do.
I would strongly caution you against using their product on any vehicle where esthetics matter.
Ouch. Not to mention if anything goes wrong or bad with that device, what you going to do next?

Zar,
How hard is it to get to the switch, do i need to pull the dash?
If so, how hard is it to remove?
Might there be a better place to intercept that wire?
For me it was easy and worth it. Remove the stereo bezel, remove plastic steering trim to get to the screw for the carbon trip piece, take the carbon trim out with the button. Might be slightly uncomfortable to splice into the red wire because of steering wheel in the way but nothing too hard. Thats it really, than just wire switch where you want it, its the matter of running the wire where your switch will be.

Could the black ground wire going to the plug be the splice point to disable the switch? Seems like it would be safer to route a pair of ground wires through the car instead of a 12V.
Test it, unplug the black wire and try starting the car. Than try remote start it and press the brake pedal afterwards and see if it shuts down. I did 12V because it's constant 12V, meaning the button is complete off if theres no power to it. Try it, I don't believe it will do anything, but it could work.

Trackhawk push/start button kill switch

Hello my names Sean new here with an 18 trackhawk. My dumba** removed the ground not the positive off the battery like an idiot. I went and put the red wires back together on the push/start first and put the ground back on the battery. Now seems like I have no Power on the push/start button. My Key fob doesn’t do anything no unlock/lock nothing. Interior Lights come when you open the door. Speedometer says push brake and push start to start but nothing happens. No Acc or run or start. So being that I clipped the red wire while the positive was still connected is there any way this thing went into theft mode or something like that? Any idea what I should I do? I am completely stuck. Anything helps
Check all the fuses would be the first thing, look at them very closely, sometimes they seem fine, but they're not. The fuse I marked below would be the first thing that goes Fuse 51 (10A) it goes directly to the button.

It was exactly what you said it was. Fuse 51 is a micro 15amp. Replaced with another and bingo! Key fob and push to start works again. Kill switch to red wire on push/start button wired and working. Thank you !
Nice, glad I could help. As you can see the fuse looked to be fine, but was actually bad. I've seen that before, just something to keep in mind when troubleshooting.
