Bobcat 642 Gas Engine (+) Coil wire

[Schifference]

Has Ford engine.
Missing wire from (+) side of coil. I don't see the wire. There is no wire just a broken connector. What color wire should I be looking for and where does it come from?
Thanks.

Had a run and stop situation. Would run a few minutes sometimes good then quit under load and not start. Anyway what I did to eliminate the issue is cut off the pin on the anti-backfire solenoid, take the wire from that and put it to a new fuel pump and to the (+) side of the coil. Runs like a top now and it starts and stops with the key.
