I am looking for a wiring diagram for the climate control on my car. I don't think I am getting power but there are a lot of wires going into and out of the unit through 3 connector plugs and I don't know which one is +12v and -12v. Does any one have a diagram.

 

volvotips.com has wiring diagrams for the 850s

 

Thank you. I'll check that out.
