want to install some kill switches on my 91
#61
SPDT toggle, rated 15 amps, interrupting the fuel pump this way:
- cut the wire to the fuel pump and connect the fuel pump side to one end of the switch and the other end (should be coming from the Circuit Opening Relay) to the center terminal of the switch... and connect the horn to the other end of the switch.
If the switch is set for the fuel pump to work, the truck starts. If the switch is set the other way, the horn goes off when the thief tries to crank it over or tries bump starting it and the AFM turns the COR on.

I'd like to do this and also wire a push button into the starter so you have to flip the fuel pump on and push the button while cranking to start.

Put 3 switches on your dash and have them in sync, for example
the first switch would ground out the distributor, and #2 and 3 would have to be lined together to power the distributor. And then put another under the dash for the power to the starter, plus put a battery shut off switch in your glovebox like the one pictured in page 1. So you would have to key up the batt switch in the glove box, thurn of the dist ground switch and line up the 2 dist power switches, and then turn on the starter switch. Easier said than done.

This is it. Just find it.
It was bolted in the empty hole next to the heater fuse
I could be wrong though.
Maybe you are grabbing the clutch cancel wire before the COR I guess essentially doing the same thing. Thats probably a B/W wire.

Not to be a prick but I dont think this is correct.. I think you want to look in the passenger side. The COR (fuel pump relay) is above the speaker on the passenger side. Find the blue wire there coming from the COR. You;ll know its the COR because it will say Circuit Opening Relay and click when you turn on the key. Easiest to remove the glove box to get to it but you could find the wire running down the side sill panel as well.

ok well i dont get the point of the relay? i was just going to put the switch in between the wire and thats it. well the idea was that when the switch is off the pump wouldnt work and when the ingnition was turned on the horn would sound. not sure how to do it but i liked the idea. found the COR but i just havent had time to get at it yet. going to try this weekend.

the purpose of the relay is that your switch maynot be able to handle to current flow that the pump would draw. By using a relay you are just using the switch to engage the relay and not handle any current flow by the pump. That now flows through the relay instead,

it depends on which wire to the COR you are interrupting. if its the main then yeah, you will need a relay, but if its just the 12v that flips the relay on, a switch inline is probably fine.

So I tried this today. Didn't work. Then I tried to learn some things about relays, and I'll get it right tomorrow. First off, why are you putting in a switch to the ground of your 2nd relay? You might as well just switch the ground on the COR right?
But if you're putting in a 2nd relay, why not just put that relay between the switch and the pump on the power line?
I'll keep you guys posted.. got a lot of useful info off this site, but this is getting weird.

works now
even without a switch, this wiring scheme did not work. I couldn't tell you why, but it didn't trip the new relay at all.
So I put the switch between COR and the new relay and grounded the circuit instead of putting the switch there. works great. 92 v6 blue wire from the COR. that is all i know!!
it's similar to page 13, starter kill via hidden switch on this real handy pdf http://sonolithics.com/files/bosch.pdf
oh and btw the generic 5 prong relay from autozone didn't work either, it switched the pump on and off like a flasher when i had the switch turned on. used a bosch and it works great.
from the research i did, there are theoretically a lot of "correct" ways to do this, but i'm just sharing what actually worked, and what did not work.
good luck, wiring is weird.
