i want to put a fuel pump kill switch on my 89 camaro.....anyone have a diagram of how to do the wiring?
i see this guy on ebay selling them for like 40 bucks plus shipping but cmon! its a 5 dollar switch and like 6feet of wire! less than 20 bucks if you ask me! any help? tips?

 

There's a tan/white wire running under the carpet along the driver side door. That's the fuel pump power. If you tap into it, that will disable the fuel pump.

However, it's not fool-proof. Same thing as disabling the starter circuit, for example. It can be bypassed. So it's up to you if you just want it for the looks or bragging rights.

Your car should have come equipped with VATS and as long as it is working properly, it will disable the injectors. That beats any other kill-switches because there is no way to bypass it.

Hope this helps.
