Good day.

How can i install a kill switch, either to the fuel pump relay or the ignition? Any help would be accepted.

Any time you want to add a shut off switch to a component you need to interrupt the power supply or the ground.

I highlighted both wires. The way to do this is cut one of these wires and run a new wire for each side of the wire to a toggle switch. This way when you flip the switch on, it will complete the circuit but it will keep the circuit open when the switch is off. I diagrammed it on the last sheet using the ground wire but either wire will work.

Let me know if you have questions. Thanks

Kenny good day. obviously the wires are connected to the fuel pump .. can they be sourced further forward to make the splice? Or just remove the rear seat and trace it FWD?

Good question. You can do it anywhere on that wire. Where ever is convenient to make the splice. Just make sure you are soldering and heat shrinking the connections so that you never have an issue.

Hello Kenny.
I have another question.

What about connecting a inline fuse and a relay to the circuit ?

This circuit already has a fuse so you don't need to add another. All you are doing is adding a switch so the circuit is protected.

Let me know if you need anything else. Thanks
