Sorry to start another thread about this, but I just wanted to let everyone know that I put in a new fuel pump kill switch this weekend and it works fantastic. I got all of the information off this website, b/c H-T kicks ***, and it was such a big help. Thanks everyone for your information, if anyone plans on doing this and wants some pictures or instructions on how to do this, please IM me I will be more than happy to help.

 

An instructional write up would be nice. This may be a future mod. Have not thought about it much yet.

 

This was one of the easiest mods I have done to my car yet. Even easier than installing an intake. I went to Home Depot and got a black toggle switch, b/c it matched my interior, and some extra wire. Cost was about 5 bucks total.

1. Remove rear seats
2. Find wires (covered by plastic tubing) coming out of fuel pump.
3. Cut yellow wire with green stripe and silver dots
4. Start car to make sure you found the hot wire for the fuel pump.
a. If car starts and then shuts off you have done it
b. If car continues to run then you cut the wrong wire
5. Find a place to install switch (mine is in my back seat area somewhere???)
6. Cut two lengths of wire that will run from the switch to your cut power wire for the fuel pump
7. Connect one wire to one end of the power wire of the fuel pump and the other end to the switch
8. Repeat with second wire.
9. Run switch, make sure to hide it
10. Put seats back together
11. You're done....easy as can be

 

thanx for the info

 

Wouldn't you be better off tapping the hot wire somewhere else? I mean most people I assume would know where the fuel pump is and the placement would make it easier to find the leads and splice them.

 

plus the use of a relay might be smart

 

both of those are valid points, but I got a switch with a 20 amp fuse in it...so the relay was no problem. and if a thief actually goes to the trouble of taking my backseats out to find the fuel pump and the wires that run to my kill switch then he is very brave b/c it will take him some time to get the back seats out....plus if he goes to that length then he can have my car....I am fully covered in insurance so I would actually make money....and this is just a theft deterrent not a fool proof plan...most thieves will look around for cd's and **** and then run if they start the car and then it shuts off two seconds later

 

is a relay really necessary.

 

not if you have a big enough fuse

 

whats a big enough fuse??

 

well i have a 20 amp fuse...but i hear that 10 to 15 is okay

 

it has nothing to do with a fuse. Switchs have contacts, which can handle only so much of a load. if you go over that they can burn up or "weld" themselves together (too much power in too small of an area). The relay allows a smaller switch to turn the relay on and off, while the higher power rating of the relay allows it to handle the load.

 

so a relay is necessary?

 

Depends on the amperage of the "hot wire"

Try using a voltmeter to measure the amperage and then pick out a switch accordingly

 

you can find that wire under the dash by the fuse pannal

i had to tap it for a secondary relay for my inline fuel pump to i wouldnt over heat the fuel pump relay system and burn something up

 

I searched high and low and found a 30 amp toggle switch at an auto parts store. It was about $5

 

So to sum it up, unless you have a switch that is rated to handle the amperage that is going through the circuit then yes, you need a quality (bosch) relay. Also, if you dont have a multimeter or dont know how to properly measure current in a circuit then find the fuse for the fuel pump and get a switch or relay that can handle that rating

just a side note
'Depends on the amperage of the "hot wire" Try using a voltmeter to measure the amperage and then pick out a switch accordingly'

You have to you an amp meter, not a volt Unless you know the total power or resistance and voltage and use ohm's law.
