Where is the 20-pin connector that the shop manual talks about to test the combi. switch?

 

Since I know you have a manual, I assume it wasn't there when you pulled the lower dashboard cover and knee bolster? Probably have to pull the steering column cover also.

good luck

 

I found the combination switch connector. It was the blue plastic plug that had about half of the 20 pins filled. It was mounted left and below the steering column behind the knee bolster. There was another 20 pin connector (light green plug) in front of it, so that is why it was confusing.

The drawing in the shop manual didn't make it obvious which connector they were talking about. After I matched up the wire colors to the pins, it was pretty obvious which connector led to the combination switch.
