87 351 bronco yellow with light green trace on both pins coming out of the tfi box. Diagram says this wire goes to the ecm but does not show a connector in the middle.

Looks like the plug for the a/c compressor clutch...

It might help it the picture wasn’t zoomed in so far.

That's the SPOUT connector. It just needs a jumper. It's designed as a way to disconnect the computer from the distributor mounted Ignition Control Module, so you can set timing. With no jumper in place, the timing isn't being advanced by the computer. I bought a molded jumper from CJ Pony parts for mine, then I found mine in one of the door pockets.

My Bad. My later trucks Spout connectors (and TFI module) are below the driver's side hood hinge. The pic showed the front of the engine/timing cover on the driver's side, right about where the AC compressor would be.... Wasn't thinking earlier years with the distributor-mounted module, although the wire colors should have jogged my memory...
