Ran out of time to work on it for the weekend. However wanted to post this in case somebody else came looking.

When referring to the mercedes benz repair manual and troubleshooting guide in relation to the KLIMA control box, it refers to them by pin number. I spent some time troubleshooting and putting it together but finally figured out which pin was which.

This again was for a 1985 mercedes 190E.
