There are four connectors that serve sensors in the main wiring harness on a manual transmission. One is the speedometer. The other three terminate to sensors that screw into the trans. All three have the same termination that will bolt into any one of the three holes in the trans that server them.

Does anyone have a pic handy or know which connection goes to each of the three spots? I cannot for the life of me find it in any of the service manuals or online.

 

this is all I could find so far...still looking

 

Thanks for trying. Still looking here as well.
