So after checking and finding out what the problem with my heater only blowing on low was I started poking around and noticed/came upon a few other things.
This is a bit long. The truck is a 1978 F150 4x4 with AC but most of it is not connected.

First, on the side of the carb is a black cap, that has 2 connectors on it. One has nothing plugged into it. What should be plugged in here? Carb model is 9605S.


On the other side of the carb coming out of the firewall is a small chain. it appears that is should be connected to the carb but is not. See the pic.


Next is the coil. There is what I think is a resistor on top of the coil it has a wire coming out of it then a connector then a wire that is not attached to anything. I looked around and do not see anything that it would be attached to. What is this for? Where does it go?
Next is a connector coming out of the firewall on the passenger side. the connector has a length of wire coming out of it and a female connector at the end, this is not plugged into anything. What should it be plugged in to? The missing connecting on the carb possibly?


Finally, there is a connector that has two wires connected to it. i followed it back and it goes to an electric fuel pump. There is still the manual fuel pump connected though. When I turn the ignition on I do not hear the electric pump working. Any way to tell which one is actually providing fuel? Other than taking one or the other off?


Any help would be appreciated.

 

the thing with the chain on it is a cruise controll servo. it hooks to the throttle linkage on the carb.

 

The black disc with the red wire is for your choke, it's missing a ground wire.

You can make your own and ground it to the block or the battery.

Holley.com has you tube videos showing how to set up your choke adjustment correctly.

If you have an electric fuel pump, just follow the wires from the pump and see if they end at your loose connectors, could be the PO went with a electric pump then either the PO or the pump gave up the ghost and they went back to a stock pump.

 

On the device on the coil, what color is the wire, and can you show me a picture of the device that you call a "Resistor".

It sounds like it's the Coil's Radio Interference capacitor. But need a pic of it to determin.

 

sorry forgot to add it to the post.

 

That'd be it. That's the noise supression capacitor on the coil. Looks like the wiring is a bit frayed.

 

what is the other end supposed to connect to?
sounds like it is not exactly necessary?

 

The other end connects to the positive coil wire at the coil connector.

It's job is to remove RF noise so your radio in the cab will not have ignition interference.
