Yep Les, I understand that. But the dim headlight on sidelights uses the dip wiring.
If I use the original dip wiring to trigger the new dip relay, then when I turn the side lights on, the current for the dim headlight will trigger the relay and turn on dipped lights.
So I suppose the real questions are : 1) on an '86 90, would the 2 white sidelights alone (without the dim headlight) meet the mot requirements ? and
2) what's the best way to wire out the dim/dip box behind the dash ?
