I think there are in the 85 model year alone two possible antenna configurations and two possible remote switch (auto, up, down) configurations with different color wiring harnesses.
I found out the hard way when I swapped my antenna recently with a recycled one. One possible model controller is solid state (black, black, yellow green, and blue is power). One possible switch model has the radio lead coming into terminal one and another switch model has the radio lead coming into terminal 1.
If you do it wrong your antenna will cycle and act funny
I tried to "think out" the schematics when I finally figured out that the 85 sevice CD is wrong. In the end I just worked the permutations.
Has anyone else run into this?
