    Electrical question?

    hey, for anyone who knows, coming off the back of the lheadlight switch, there are about 8-10 wires, most of which go back through the firewall, and the rest go to other places throughout the dash. What im wondering is are these wires running to other places power wires to lights for the rest of the dash? id follow em and find out but they run through different harnesses and theyre hard to follow. Thanks in advance.

    btw its a 90 325i, not that i think it matters, but just in case

    ..what are you trying to do? Why are you trying to ID the wires?

      Do you have a bently?

      I would have to check to make sure but i think it might help you out a bit with identifying the wires.

      Good luck.

      I have an ETM at home (im at school) so i will check for you but the CD manual is pretty much the same thing as a bently but makes finding wire schematics and such alot easier then flippin through pages.

        It does matter, they fog light setup is different on older and newer cars, and the wire colors are different as well.

        Unplug the harness to see if it powers any other part of the dash. I know several control the fog light switch and the parking lights. Check my site under independent fog lights in the tech section to see which wires.
