    Wondering where the Reverse light wire is located? and what color? I put in a B & M Megashifter, but can't find the Reverse wire to splice into the shifter. My Haynes says its located under the dash and is light green in color. Every green wire in there was not it. I cut them all, but the Rev. light still worked (used the column shifter to check)....(yes, I spliced them back up).
    Anyhow, thanks for anyhelp. Oh, it's an 89' K5, with an R4.

    The reverse wiring usually goes to a half moon shaped switch on top of the column. Keep in mind this ALSO has the park neutral switch.

    Quit cutting wires unless you know it's the right one. And if you're gonna be wiring things up, a service manual would be helpful.

    I looked there, but didn't see anything..hmmm...do you know what color it is?

    Don't have a service manual...all I have the Haynes...
    The wires I cut, I spliced back with a solder...it was tough, (short wires),but it's all good.

    '85 is the last year I show Dark Blue and Light green and it is the "U" shaped switch on top of the steering column.

    I have the schematics from a 1990Chevy.

    It shows a dk. blue and a lt. green connector at the Backup switch. Which is located on the steering column, It's on the same part as the park/neutral switch. The dk blue comes from the fuse block to a this connector. The lt. green is also located here and then runs to the rear of the truck.
    Would you like me to scan the drawing for you and e-mail it to you.

    Hope this helps
