I’m trying to wire up a toggle kill switch but I don’t know which wiring harness I need to tie into underneath the dash. I have a few different harnesses up under there.

i plan on just running a switch to the fuel Pump wire. I have a multimeter and have been looking for the fuel pump wire that shows 12v once the ignition is on.

Can someone please point me in the right direction? Thanks a lot.
