I've seen diagrams like this before, unfortunately the objects on the van don't look like the drawings. I haven't found the canister yet, but I'm sure it has one. I have found the PCV valve and connected it. The throttle selrnoid is not connected. Is there a way to tell the difference between manifold and ported vaccum? I need to know what the deverter valve, throttle return control selenoid, solenoid vaccuum control valve and electroic speed sensor actually look like. Your last two drawings look to be more realistic. I'm guessing that carb port M and L are the two large tubes at the bottom front and rear of the carb, ports B must be the one on the front top but H I'm unsure of.

H is on the front right but could be not used. You will have to hook up what you know and start from there.

Unfortunately the guy who took it apart isn't here, so I don't know very much. Is carb port J on the carb or are H and J part of a splitter? I really like your answer, don't get me wrong. I still don't know what the deverter valve, throttle return control selenoid, solenoid vaccuum control valve and electroic speed sensor actually look like.
Thanks Roy

This looks like what I've been looking for. It will take me some time to digest it all. Can you tell me what book it came out of? It will not allow me to save the document.
