Noob question; Installing intellitronix digital gauge, (tw: LOTS OF DUMB QUESTIONS)

That dimmer controlled power then leaves the HL switch on TAN, and goes TO the fuse box, where the small INST fuse takes that power and goes out to all dash dimmer controlled lighting on ORANGE wires. If you look under your panel, there will be several orange wires connected to one fuse.

Ok so I need to find the tan wire from the HL switch and before the fuse box, and splice the dash dimmer wire to it?
