Like the title states i have 3 wires going through a plug that i have no idea where they go. They were all tied into the main power line coming from the alternator. I'm sure they need to get fuseable links of some sort but I need to know where they go and what size fuseable link.

It's on the passenger side fender next to the other 2 wire plug that actually goes to the alternator. Red wire, yellow wire, black with a yellow stripe. Could somebody go out to their truck and maybe take a picture and let me know where the wires are supposed to go. I even found a 78 f150 in a junkyard and this plug was not on the truck. I have thought about just putting them to the battery side of the starter solenoid. That's pretty much where they were before with no fuse, fuseable link or anything.

This next picture is the both of them together the green/ red wire is to the alternator and the ignition switch. The white black wire goes to the choke and the alternator.

It comes out of the wire harness and goes?

Thank you
Bud

Hi Bud,

I just took a picture, the 3 wires are in a bundle that goes to the alternator, maybe you mean the other way.

Let me know, I can have another look

Cheers
Jim

Thank you both very much Jim your bronco looks a lot better taken care of than mine i am jealous. The wiring diagram has helped. I'm thinking c206 is this plug and the red and yellow wires are what controls the ammeter and I need to keep them unplugged because the ammeter can't take that kind of output from the 3g (need a volt meter but that's another thread there's many dash gauge options but im not decided yet). So the black/yellow wire runs off of the page and goes to the ignition? It probably needs a 14ga fuseable link im guessing and put on the terminal on the starter solenoid. Then I'm golden. Everything else is hooked up already. Actually I need to disconnect the red and yellow but hook up the black/ yellow stripe wire. Thank you guys. Finally figured this out i think

Ok i have one more question. The choke wire (white with black stripe) at plug c212 also has another wire in the plug a blue wire that is not labeled in the wiring diagram. It is a keyed hot wire not sure where it goes or comes from i looked in all of the wiring diagrams in the link miesk5 provided and can't find anything. It is a keyed hot wire that currently has my choke wired into it.
