After Leon made me pull out my Bentley for that pressure switch question, I am reminded of a quirky thing on my engine I've been meaning to ask about. I have a stock '69 Fastback, MT, with a later (71? I think) case and '69 FI system. I have no trace of any kind of cold-starting device or relay that I guess was optional on the 68-69 cars. But I *do* have a thermo switch just like the one illustrated on Fig 7.10 in Bentley. And it has a wire going into the wiring harness. Is this thermo switch doing anything? From what I have read, this switch is used only to trigger the cold start device. Does it do anything else? Maybe that part is just a leftover from the 71 case that was used in a past rebuild? -Mark Fuhriman ------------------------------------------------------------------- Search old messages on the Web!
