Does this work as a fuel cut-off switch? Will i need a fuse or anything? Or do I just splice the switch into the fuel pump wire? Thanks.

 

I believe the fuse for the fuel pump is rated at 15A. Make sure those switches can handle that kind of power.

Question: Why do you want to put in a cut-off switch? It's too bright and big to hide it for a extra measure of security.

 

Still going to hide it, just like that kind of switch. Will an additional fuse be needed or is it built into the switch?

 

kinda big switch to use as a fuel cut off and hide IMO

 

Use a relay instead...that's my suggestion. Then you can basically use whatever switch you choose; i.e., a small, hidden one without having to worry about too much current going through it, thanks to the relay.

 

How do you wire this up? I never messed with relays before.

 

Super easy...first off, do a fuel kill search in the audio, security section...Tekken gave out some great ideas. But the basics are the same for all of them...

Get a Bosch relay (partsexpress.com...cheap)...there are 5 pins on it.

Pin 86: 12V power goes here, install a switch before it so you can cut the signal. Make sure this signal is an ACC/IGN power signal, as in, it has power when the key is in both positions.

Pin 85: goes to ground, this is the other end of the circuit in Pin 86.

Pin 87: put one end of the fuel pump line (yellow/green wire) here

Pin 87a: leave it alone

Pin 30: connect the other end of the fuel pump line here...

And now you have a fuel kill relay setup. When you turn the power on w/your switch, it power the relay via Pin 86 and 85, and when those have power, it will connect Pin 87 to 30; therefore, compoleting your fuel pump power When the switch is off, Pin 87a will go to 30...and since nothing is on 87a, the fuel pump will be dead.

Again...that's the basics.

 

cool, where can i find a 12v power wire source?
