these days, you can never be too careful. especially with our beloved jeeps. so i decided to install a "kill switch" on mine. i didnt find any write ups on how to do it here, so ill write one. ok its not really a kill switch for the engine, but more of a kill switch for the starter. when it is off, the ignition will turn on, but it will not crank. so even if its hot wired, it aint gonna start. heres how i did it:
its a pretty simple concept. i just routed the starter solenoid through a $5 toggle switch, which i mounted under my dash. so the starter will not receive the "command" to crank the motor
-two appropriate lengths of electrical wire (i just happened to use a 3 wire cable i had laying around, but the 3rd wire wasnt used)
-2 ring terminals
-1 spade terminal
-1 butt connector
-1 single pole, single throw toggle switch
step 1: remove the wire from the starter trigger terminal on the starter solenoid. heres a picture:
if your are laying under the jeep on the passenger side, you should be able to access it straight above the exhaust.
step 2: theres many ways to do this, but i cut the old connector off the wire i removed, stripped it, and used a butt connector to connect it to my red wire that goes to the switch.
step 3: put a spade terminal on my black wire (returning from the switch) and connected it to the terminal on the starter solenoid (the terminal i removed the original wire from).
step 4: i routed my cable along the original wiring harnesses running along the firewall, and down through one of the rubber firewall plugs on the drivers side.
step 5: once inside the jeep, i installed a ring terminal on both wires, and hooked them up to my switch.
step 6: test it out before you mount it to make sure everything is in check. like i said, with the switch off, the ignition will go on, but it wont crank. with the switch on, it will start just like normal.
step 7: now just mount your switch wherever you please. obviously somewhere hidden is ideal, but its up to you. i mounted mine up near the steering column, so all i do is reach under and flip it.
i hope this write up helped you, any questions feel free to ask
