    Hi I have a few questions regards my WR390 1980 wiring that I was hoping that someone might be able to answer.

    Does anyone know what the white and yellow wires in the pic are for? I want to connect the headlight and tail light, I assume there is a regulator missing but on ebay I have seen 1 and 2 wire regulators for sale and wasnt sure which type my bike needs.

    Also does the 1980 use 12 volt lights?

    Was there ever a light switch on the handlebars or are the lights just always on.

    Does anyone have a schematic or wiring diagram for this model?

    Awesome info Visiteur1948, but still not sure what the white wire is for, you mentioned "stop" Is this stop lights?

    You need the one wire regulator. Yes lights are on when the motor is running. You can wire in a switch if you want. If you want a brake light the white wire is for the brake light. Other than that just use the yellow wire for the head light and tail light. Yours is 12 volt system. I have regulators if you still need one.

    Perfect thanks Motomwo, Thanks for the offer of the regulator but I have already bought a bargain on ebay. I will just wire the lights direct and skip using a light switch on the bars. I wont be licensing the bike so no need for a brake light

    I'm confused also. The 82 83 diagram applies to me as my motor is either 82 or 83. The motor has 2088 stamped on it that I thought meant cr but it has an sem ignition of a wr.

    From the stator I have two free yellow wires with female bayonet type plugs........the rest of the 3 wires goes to the black coil.....they are green, black, and a reddish brown ones. From the coil comes 1 new colour of a light brown orangish colour with a Male bayonet end. I also have a loose alternator with a yellow wire coming out with a Male splade connector.

    If I want the front and back lights to work and a kill switch what do I do?

    Secondly if I want the whole hog.....as above plus brake lights and indicator lights horn etc what should I do and is there an easy wiring harness around for this?

    Hope it make sense?

    Hi everyone,
    I have 1980 390 OR
    Im actually starting on wiring headlight + brake light.
    I thought my system was 6V but im reading here that 80s models are 12 V ? Im still not sure...

    If mine is 12V is it ok to use LED lights for the setup ? would that be ok ?
    Do i have to add anything else besides a regulator ?


    Thanks in advance
