That's the SPOUT plug. You pull that plug out when you are checking or adjusting your base timing.

You unplug it to stop the ecm from controlling the timing.

Timing has to be set with that unplugged. Assuming you know how to using a timing gun just set timing at 10ºBTDC and then plug the spout back in.

Until you check it, you're guessing it's not right. By the way, your SPOUT plug pic has already gone "Viral":https://www.f150forum.com/f10/truck-...y-alive-67376/ I'm permanently borrowing it too!

Those wires look like my personal fav's. "Superconductor's"
