Fuel pump kill switch

[troopa]

I want to install one of these on my car and I'm just wondering if this is the easiest/correct way to do it...
Do i simply cut the wire at the rear of the fusebox going to/coming from the fuel pump fuse, extend both wires and add them to a 2 prong rocker switch?

Nope as it's a high current circuit. You'll need to do it via a relay. Why do you want to?

Security. Ive seen other people do it like this. It only runs on a 20amp fuse. Surely a 25 amp switch could handle it?

you're key is coded which more or less kills the fuel pump anyway if someone tries to start it without the key.

But what if they have my keys?

 

[jbh]

do you think someone has a key? if so im sure there's a way of deleting keys from the system but I could be wrong.

 

[troopa]

No i just mean if someone managed to get my keys. No alarm disklok or any other type of security will stop them if they have the keys. So i wanted to do a fuel kill switch and hide it. Wont start then.
All i want to know is if i can put a 25a switch on the fuel pump wire coming from the fuse.

If you can get the clocks to turn on, (as in you would with the key, preheat ) snap n cap or slidhammer the ignition you can get them away
on immo1, and immo2!! in fact i'd add a kill switch to any of my cars , as with an item anyone can buy from the net you can get just about any motor away!!!

I would tap into the circuit that feeds the fuel pump relay.

Its low current and would kill all the injectors, pump, etc together.

Saves running meaty wires around the car.

I'd extend the live battery lead in the cabin , and use this hidden under the dash, or use a cigar socket cover to hide it in plain site, also for the relay get an air bag on/off key switch and wire that in to cut the relay! http://www.ebay.co.uk/itm/Battery-I...18121&pid=100338&rk=13&rkt=25&sd=131556619585
