The original headlamps for the 39 120 were bulb and reflector. Sometime in the past they were replaced with sealed beams. The new wiring harness is setup for the old system, which had four positions on the headlight switch - 1. parking lights, 2. City driving 3. City high beams 4. County driving, with the left lamp being dimmed with the dimmer switch. Any suggestions on how I should wire the sealed beams in? thanks - that's all for tonight!

I think the 4 wires are high, low, ground, and parking lamp. The town and country situation is handled by the headlamp switch and dip switch. You will not be able to run the parking lamp bulb in the factor configuration with sealed beam conversions.
