Cool High Beam Switch Wire Location - Need Help

I'm looking for the high beam wire off of the switch. I want to use this wire to hook up mounted lights on a brush guard. If anyone knows the color or location of the wire please share. I've read the wiring diagrams in the Haynes Repair Manual and haven't found what i'm looking for. If anyone has done this before is there a better wire to use other than the one im looking for, the goal is to have the lights come on with the high beams and also have a switch i can turn them off with. I already have an on-off-on switch with power from the battery so i can turn them on and off as i please, but i cant find a wire to run to the switch so they come on the iwth headlights. Any help is appreciated, thanks

Have ‘99 diagram, should be same as ‘00.
You’re looking for a wire from the multifunction switch not the headlight switch. You’re using this only to trigger the relay, right? The wire coming out of the mfs will be GY/OG gray w/orange stripe. If you pick it up coming out of the fuse box that same circuit wire will be LG/BK light green w/black stripe. Good luck!

Just pull it off fuse f16 to trigger your relay.

To understand, you already have the aux lights operational with a switch and you want to "enable" the lights to operate with hi beams?

Why not just tap into the harness at one of the headlights to trigger your relay, having the relay interrupt the existing power to the aux light?
Aux lights will only energize when hi beams are activated and the existing switch is turned on.

Wanting to put a switch inside, it would make more sense to tap into an interior wire to trigger the relay. Then you run one wire out instead of a wire in and a wire out.

Sorry,I understood that OP had an existing switch wired to battery power. If so, putting a relay underhood would eliminate the need for any more wires through firewall.
use #1: wire relay in series to existing power wire with hi-beam wire tapped as trigger. Switch and Hi-beams must be on for aux lights to work
use #2 wire relay in parallel to existing lighting circuit using battery for power and hi-beam tapped as trigger. Switch will turn aux lights on and off & aux lights will go on whenever hi-beams are activated.(switch will not control aux lights when hi-beams are on)
