Looking at a wiring diagram for my 84 bird I can not figure out where the blower fan should be grounded. I have the grounding wire hooked up on the blower housing. It appears that the ground wire is in a 3 plug connector (Black, Green, Blue) that travels to the other side of the wiring harness and comes out with the plug for the coolant temp sensor, another connector (blue wire), and two bare wires (pic below). The black bare wire will ground the blower motor. I believe these are the wires for the A/C compressor. I do plan on putting the A/C back in. Can anyone help identify these wires and where they go.

 

The small blk and green wires are for compressor clutch lockup. Your fan should work independent of the AC system status. It has it's own heavy black ground, which can be grunded anywhere on the car

 

Okay I found the culprit. Cut ground wire.


The ground wire goes from the high speed relay to this harness. What is it? Looks like someone did a real hack job on this harness. The power wire from the starter was replaced with this connection and the original was taped off.



Coming out of the harness is the green and blue, and two grounds one for the blower motor and one that I thinks goes to the A/C compressor. This would also ground the blower motor.

On the other side I have the green and black which look like they are for the compressor, the temp sensor wire, and a blue wire with a pigtail on it. What is this for?

 

"Looks" like the power wire for the throttle kicker.

Where would this plug into?

 

Front, driver's side of the carb. The kicker is used to bump the idle up (with the help of the accelerator) when the AC is used. Following is the Edlebrock version:

Did you know I had an edlebrock carb? Can I run A/C with out this? $112 seems likes a bit much

 

I didn't know you were running an Edelbrock. I just thought a visual would make matters clearer--and I run the above on my Holley. When the AC comes on, you may find that the idle will drop enough to be problematic. Try it and see.
