In reference to differences in wiring between dual lights and single lights, I may be miss stating here because i am just thinking about this without checking a schematic, the significant difference between 100/6- early 3000 and the later 3000 (BJ8) is the later dual light set up does not have the turn/brake light relay on the inner left front fender. Also the later cars have some changes to the wiring behind the dash. Having said all of that, here are my thoughts about what the car might have or need. The turn/brake light relay is really only needed for the rear lights where by the one bulb is used for the brake light and then also the turnsignal. If the car has two lights on each side in the back, a separate brake light and also a separate turnsignal light, then a relay is not needed on the left front inner fender panel. So then there is none there and maybe never was. The front turnsignals would work without a relay because they don't serve a dual purpose of turn and brake. So if the car had a later BJ8 front Shroud and a single light front shroud was substituted I believe the only wiring change needed would be that at the front lights, the wires that were in a second lamp socket would then be terminated in only one light socket. I might be all wet on this, I didn't check any schematics.
