I cannot offer many suggestions. I am a Jeep CJ kind of fellow.
The diagram I found you is from "mitchell i".
It shows everything in the front wipers. Fuses and other stuff has locations listed, also shows the wire colors.
This may be helpful for you to perform testing.
I will stick with my Jeeps. No computers, simple to repair and maintain. And last forever. My "5" is 1935 and my "willys" is 1966.
Let me know if this helps.
