Does anyone know what else is taped in the same line as the following:

2 oil pressure wires - sending unit and ground wire
2 wires that connect to coil
3 ignition wires that plug into disty

and....

2 mystery wires, that have are unconnected and look yellow maybe, maybe brown. Also one looks to be extended via some sort of connector.

And there is also a mystery wire with a male spade connector attached to the coil bracket.

Picture coming

 

 

"there is also a mystery wire with a male spade connector attached to the coil bracket." = ?condenser" connects to radio for noise seppression.
I'm susspecting on one of your black hard plastic yellow wires connects to the clutch on the A/C compressor
The spade connector connects the "condenser" to your radio.

 

Also if you're running a/c there would be some kick down mounted in the carb linkage which had a single wire connection.

 

Interesting about the radio - where might the other end of that plug connect to?

And pardon my novice-ness but where is the clutch on the A/C compressor. It has only blown hot air since I got the truck, and it doesn't get too hot where I am so I've never really looked too closely into the AC system. It would be incredible though if all I had to do was plug something in to get cold air!! One can dream...

I took it off, but I still have it. It has a bullet style connector on the end of it - not sure where that might plug into?

 

A/C clutch is in front of the compressor. The compressor is just on front of the coil. I can see it in your pic. The part that the belt pully is attached to is the clutch. I have seen one black wire with a bullet connector for the a/c clutch. #2987 is the clutch. In the 2nd pic you can see the lone wire. And that wire is routed with the a/c lines. I have never seen a a/c just start to work when the one wire gets hooked up. Normally you need to draw a vacuum on it and add freon.

 

Could one be for an electric choke ? I believe that 7 volts from the alternator goes to the electric choke. If I remember correctly

 

just rewired mine last year. Yellow is a tach wire, brown if you chase it my diagrams show #16 Red wire with a green stripe runs back to the ignition switch.
Sorry, tried to upload diagrams but PITA to upload 🤡

 

I think the choke wire is wht/blk.

 

Hard to tell from the first pic, but is that short wire with the spade connector on the end, directly connected to that cylinder/capacitor thingy mounted to the coil bracket? Looks like the wire coming out of the unit takes a hard 90 and is stuffed into that plastic connector, but I wasn't sure.
As was already mentioned, that capacitor/condenser/thingy is a radio noise suppressor. Your external voltage regulator would normally have one as well.
If the wire goes into that connector from the noise suppressor, then it probably broke off sometime in the past and was shoved into it. the end in your hand likely was originally on the positive side of the coil connector.
Looks like you recently replaced the coil's "horseshoe" connector? If so, maybe the new one only came with 2 wires total? Should have been three on your original. One would have been Red w/green for the coil positive, the other would have been either the same Red w/green, or Yellow, or maybe just Black, and have been connected from the positive side of the coil to the radio noise suppressor.

Looks maybe like your coil is in backwards, or the bracket is mounted backwards, or on the wrong side of the engine. Many of our Fords had the coil on top of the intake, but over on the passenger side. Can't remember for sure where yours would have been, but if it's just the way it came off originally, then maybe that's why the wire broke off of the capacitor. If it did...

Anyway, just some observations. Not sure where the other two Yellow wires would go. Usually Yellow under the hood was for the external voltage regulator and it's noise capacitor, or the horn relay. But I don't remember them having this type of connector, or being anywhere near the top of the engine.
Hmm, but as a last (hopefully) comment, since the wire colors on the horseshoe connector are both wrong anyway, maybe make sure that they're both on the correct side of the coil.

Power from the key via the resistor wire would go to the positive side of the coil. Along with the noise capacitor. This should be a Red w/green stripe wire. Not the Red w/blue that you have now.
The signal from the Dura Spark ignition control module would go to the negative side of the coil. Any tachometer would read from there too, but from the factory there was usually only one wire. Green w/yellow if I remember. Not the Green w/white that you have.

I could be off on my colors of course, because I'm only going by memory. But it would also not be the first time that the Chinese manufacturers got wire colors incorrect and/or backwards. And the US companies that import them don't seem to care anymore that there is a "defect" in a new part.
So hopefully I'm the one making the mistake...
