Have what we think is a 77 cab and the wiper switch disintegrated
We have a switch from a 83
The 83 has 6 wires. 2 grey, a black, a black w blue , and a pink
The 77 has 4 Light blue , a dark blue , a black w white , a light blue .
I know one of the wires in the 83 switch is for the light
But don't know which one
Is the 83 switch compatable with the 77 motor?
Or
Should I be hunting a replacement 77 switch ?
