I'm looking for a convenient place to hook up my gauge lights so they will dim with the instrument cluster. I've seen references to tying into the tan or orange wires on the headlamp switch. I have the wiring diagrams. If I read them correctly, the only way you are protected by the 5 amp fuse in that circuit is by tying into the 22 gauge orange wire? Otherwise, you bypass that fuse and go directly to the gauge lamps and ground. I'm a little reluctant to pop off the instrument cluster because I'm afraid of damaging/breaking the plastic. Can I tap into the ground side of the fuse at the junction block? Would it be that bad if I tapped into the ashtray lamp?
