Alright so ive searched and found alot of info, but nothing on my, what seems to be, too simple idea.
Is it okay, and safe, to just put a rocker switch inline of the fuel pump ground? Basically just use the switch to interrupt the ground so the pump obviously wont work.
It seems like everyone is thinking too hard about this.
TIA, josh

 

 

well, im going to be doing this today probably. anyone know if im going to blow myslef up

 

I need to do one also - what guide are you using?

 

i was planning on using the, grab the helms, find the ground for the pump, and put a rocker switch inline. But none has responded to how this would work. It seems like people are going crazy with relays and such for something so simple.

The problem with cutting the ground to anything is ground is common, and a load will try to find a ground through another path, and that can be a problem, I don't think your going to blow yourself up, but an electric device submerged in a tank of gas with 12v+ going in and no ground 94

This guy has an easy looking write up.

Judging from this write up all you need to do is locate the YELLOW wire with a GREEN stripe and put a SPST switch in between it. Seriously looks like the hardest thing is removing the rear seat.

I have also seen the ones using relays – I don’t see really why that is necessary. It is not going to slow a thief down. I think I am going to do the same basic set up as the link I posted.

"The wiring for the pump runs along the driver's side door sill." &lt;---

I would like to think if you put one of these in and hide it well along with a good alarm you can stop most thieves. Then again most people who steal cars know what to expect – that is why doing stuff to confuse them helps. A guy would rather steal a car that has a basic alarm then one with a full cut off and an alarm that has interior sirens.

Relays have nothing to do with the security. They are there to ensure that the fuel pump gets the proper current/voltage since the power has to pass through the switch now which has some resistance to it.

Security only buys time. If a theif wants something they will get it.

 

Relays also allow one to use a smaller switch since the current will be flowing through the relay terminals, not the switch itself

Relays have nothing to do with security? How about starter cut relay, or ign. kill relay. any switch has "some resistance to it" a relay is just a switch 94
