82 wiper switch in 77 cab?

[roundhouse]

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 ?

No they are different...I believe you can still get them. I know I have an NOS one in stock

It's a 78-83 wiper switch PN 459481 Sounds like what you already have. Sorry but the good news is there's a few on eBay 75-77

I apparently have the 76-77-78 version with 4 wires in an L shape plug
