I have been thinking about putting a kill switch on my 95 F150, I noticed last week when I had my dash apart that when the blank for the fuel tank switch is unplugged the truck will crank but wont start (single tank truck)
Does anyone have any thoughts if this would be a good starting point, I am guessing the fat wire going to the blank is fuel pump power.

Thanks

 

ive never put a kill switch in but i was talkin to some guys that i work with and they were talkin about actually making so that the ignition wouldnt engage unless you pushed a button which could be wired through a button such as you a/c button or something like that....theres also the option of just wiring in a second igntion so you have to have two keys to start the truck...of course the second switch being hidden where no one else knows where it is

 

i also had my dash apart not too long ago in my 95 single tank
and i found that when unplugging the blank the truck wouldnt start

i was thinking about getting a switch from a dual fuel tank truck and
seeing if it would make a kill switch by just plugging it in

if so i was going to mount it under the dash someplace so i could just
switch it and shut off fuel

 

Thats a good idea, thanks ewickj
