RE: 1978 F250 4x4, No AC, No Cruise, Manual Trans

You you help identify these wire connections?

A
B

 

I think A is the hood light power and B might be the elec choke power? But I think I am wrong on B...I need to walk up to the shop and ck my red truck.

 

I found this info.. still need help translating it..

 

"B" is for factory choke. "A" not a clue.

 

Thank you.

I found another thread about "factory" choke hook up.. B = Choke... A= ??? I wonder if there is an after market "wire input adapter" for that connection? Or should I cut and splice the wires..

Ok pretty sure 15702 is the hood light power source, at least on my blue 78 it is. And nothing connected to it on my red 79. I would use a test light to see if it is constant 12V hot, to be a hood light power source.

Is 9D857 a sort of rounded 2 prong female end connector? I have it on both trucks but nothing to it on my blue truck (w/manual choke on carb) and I have a 1 wire connector coming off it on the red truck. It is dead ended, but I bet carb elec choke.

I'd test light it to be keyed 12V power.

It's cold out, so I did not dig into the harness much on the blue truck.

 

9D857 is listed as: WIRING ASSY. (CARBURETOR THROTTLE EMISSION CONTROL SOLENOID)
