    Anyone know the wiring for the reverse lights . I have a connector that looks like it has 3 wires

    one Lime Green (Supected wire to the lights) and a Yellow and Almost Pink(?) wire that

    hooks to I am pretty sure the reverse light switch however all three are dead with ignition

    and the other wire on the lights itself is a black wire (Ground?) And am I right in assuming

    there is no electrical neutral safety switch?

    I'm pretty sure the Fisher Body Service Manuals have all the wiring diagrams in them.

    Yes Fisher isn't any help I already know Lime Green is the reverse wire color.

    But there has to more to the circuit it's not a single ground and as I said I get

    no voltage off the three wires on the Reverse Light switch. So does anybody know

    or have a diagram of this circuit ,it's not as far as I see in the Fisher manual.

    Found them I was grabbing the wrong harness it is Lime green but also dark Blue.

    I also found out my Shifter maybe because it's older won't work with the switches they

    offer for later Quarter Sticks and Q stick 2s. So I had to resort to a rather crude but effective

    solution till I find a better one, it works though.
