I've been reading up on how to put an ignition or coil kill switch into my 1970 ford f100. I think there are 2 different ways at least, through the ignition wire or to the coil - still a bit unsure if an ignition kill switch can be done on a carb engine.

On the dash, where I have my wiper, headlights, cig lighter *****/switches there is 1 missing on the far left. I haven't a clue what was there originally, but my thoughts were to use that hole and maybe use a headlight **** assembly rather than a toggle switch to rig up the kill switch. That way it looks like all the other *****.

My questions are this:

Will the headlight **** assembly work in place of a toggle switch to create a kill switch?
Can I do an ignition kill switch?
If possible, what are the pros and cons of ignition vs. coil?

 

The hole in the far left bottom of the dash was for a brake alert light.

As far as the kill switch: I would personally kill the coil. These trucks are really simple to 'hot wire' and are not secure to anyone who wants to get in. If you kill power to the ignition switch it is really easy to just jump over power and away they go. Cutting power to the coil would be less expected.

 

I have an electric fuel pump and have a switch under the dash out of site. You can do what ever you want with out fuel you won't make it more then a few blocks.

 

Fuel cut off would be good, but I don't want them to be able to leave my apartment complex. Especially because I'm surrounded by highway, so if it died out there then it has the potential to be hit - especially where I live; horrible drivers.

I think coil is the way to go. Does anyone know if a headlight switch assembly is too "high-tech" for the simple use of an "on-off" switch for the coil? Would I need a relay if I was able to use the headlight assembly?

 

if you have an automatic , you can use the neutral safety switch wires to act as a ignition cut out .

all you need is a little wire and a regular 12v on/off toggle switch
best part about this is all the wires you tap into are under dash .

 

If you have a 3 or 4 speed, then you already have a theft deterrent device built-in. Probably only 20% of the country can drive a manual transmission.
