Hi all, 1984 308 QV US: I had a leaking distributor o ring on the end of my front cam shaft, and I decided “while I was in there”….. I took out the engine, did a top engine major, cleaned or replaced or re plated all parts and hardware, cleaned 40 years of grime off the frame and repainted the bay, and I’m in the process of putting it all back together… (image of my progress attached…) Long intro to my question about the location of this differential pressure switch. As you can see in the other image, it was wire tied to the frame under the coolant expansion tank when I took it all apart. The lengths of the electrical connection wires from the wire harness indicate it can’t go much further from that area. Does anyone know or better yet have a picture of how this was originally mounted? Very much appreciate direction on this. Thank you.
