On the 86 its in one of the harnesses towards/around the battery. Generally the spout connector is located near the ignition module (generic location). Some referential images...

On early Fords,
these were mounted right on the side of the dizzy... later models up
near the core support (for better cooling). As you can see, the spout
connector is a jumper that simply unplugs... taking active control of
ignition timing away from the ignition module.
Also, juts liek a sample, I quote other comments from Ford owners...
I had trouble finding mine too. my 86 didn't have one. I traced the
yellow wire with a green tracer in it from the dist. to the batt side. Iit had a **** splice in it half way were some body cut it to set the
timeing. i put in a splice that can be unhooked easy.mine will run when
that is disconnected.
END.
