A couple (silly) questions. I am having similar issues that you did in regards to the fog and headlight wiring. Where is the switch to turn on the headlights? When i pull the turn signal lever toward me all 4 headlights come on. Is this correct? What is the other lever for (behind the turn signal lever)?
Not wishing to steal Kev's thunder but I was just passing by....
The main beam coming on to 'flash' when you pull the turn signal lever back is correct.
The other lever is your light switch. One turn clockwise for sidelights, two for headlights, pull towards you for main beam.
If that's not enough lights, there are park lights on a switch next to the heater controls. Pull out and turn left or right. Interestingly it uses separate wiring and bulbs to the side lights system.
Hope that's helped, Dan.
