    I have a yellow wire with red stripe located under my rear right fender, that if (enternal power) is applied will turn on my rear red running lights and rear marker lights. My rear lights operate normally but I am trying to find what this wire goes to forward of the wheel. The wire has a factory connector on it and will only reach to approx the top of the fuel tank area??

    Thanks

    Did you check the license plate lights? Maybe goes to them on the rear lid?

    The only yellow wire with red stripe on my '83 QV wiring diagram is between the "Warning Light Cylinder 5-8 Relay" and its dash light

    The 440/86 US 328 wiring diagram shows the wire going from the RH rear parking lights to the rear "number plate lights" as being GR (yellow/red) -- look for a corresponding connector (and wire color) somewhere up near the rear bonnet hinge axis.

    When you say "My rear lights operate normally" are you including the rear license plate lights?

    Steve,
    My rear light operate normally means: if I turn my running lights on the front and rear & sides lights turn on, if I press the brakes the rear lights illuminate brighter, I can operate the hazard and turn signals as they should. So it is how it has always worked for me. The GR (yellow/red) wire is traced back into the rear bonnet but I am reluctant to cut the jacket covering the wires so we applied 12volts to the wire and the rear taillights (red) and rear side markers turned on. The problem lies with I cant see where the the wire should hook to.

    Crowndog,
    I will verify the license plate light and will update with my findings.

    Thanks

    This is the same question that I was asking -- do your rear license plate lights come "on" when you turn the parking lights "on"? (they should).

    When I was testing my rear lights, we had my deck lids removed and the other end of the wire wasn't there so I didn't think of the license plate light. IT was the missing link.
    Thanks to all who helped.
