ECS boost gauge not lighting up with headlights only parking lights
Is anyone having a problem with the ECS boost gauge not lighting up when switched to headlight position ONLY? The gauge works perfectly and lights up ONLY when switched to parking lights.
I have an 02 A4 1.8t. Quattro
I wired it like the instructions said, and Josh at ECS Tuning said my headlight harness is for auto on headlights, which it isn't.
I wired it as though it was for a NON auto headlights on switch

black red *run wire to keyed on 15amp fuse if you have auto on
