Headlight switch - 75 Duster - Stumped...

Understood. I'm just thinking ( possibly wrong, of course) no power tan wire coming from the headlight switch, that I need a switch? The 20 amp for the taillights is good . Is the breaker in the switch accessible? Much appreciate your knowledge and time!


OK, you "should" have started your own new thread. So, what does NOT work exactly?

Here once again is the breakdown. B1 is headlights ONLY power TO the switch. Do the head lights work? then forget about that part

B2 / park/ tail/ dash lights ARE A SEPARATE SWITCH completely "in the same box"

B2 is powered from a fuse and is hot at all times. Obviously, park is only hot in the park position. On that 74 P should not be used. Both the park and tail come off the tail lamp connection, so they are both on with either "park" position or "full on" position

The tan is the dash light dimmer OUTPUT from the switch and is hot ONLY

with the switch in either park or headlights
with a good fuse supplying B2, so the park/ tail lights must be working
with the dimmer control turned "left" for brighter dash lights

That tan then feeds TO the INST fuse in the fuse panel and from there out to all dash lights
