Need help to pull a wire from engine compartment fuse block to interior.
I would like to tap on the Headlight fuse and connect to an aftermarket LED for light up the room when headlight is on. Thanks.
you should also be able to tap off the wire somewhere inside, behind the dash, that comes from the headlight switch rather than trying to breach the firewall
There is a round tab on the top of the wiring grommet (engine bay side) if you slice off the tab you have a direct hole through the grommet while not harming anything within the factory wiring.
Will it do you any good to get a wire from the engine compartment to the BACK inside of the car? If it will then check page 7 8 and 9 of this document.
