If she has the newer type III system with a monovalve, where is it, and what does it look like (how many hoses/wires are coming out of it)? I don't see the bracket for the servo, so it appears to be a different setup than the1978 300CD that I had.
It is different, and has a monovalve. It's on the firewall, has a 2-pin connector on top and two hoses coming out of it. And that's all. Rejoice! -- Jim
