Hey everyone, long story short, my grandpa gave his 68 f250 to my idiot cousin who basically frankensteined the poor truck but luckily it is now in my possession. Ive done so much work to get it restored and running right again and my next step is putting the AC unit back on. Inside the cab nothing was messed with but he took the unit out from under the hood. Could anyone please take good detailed pictures of what theirs looks like and how the braces attach and how the belt is routed I would greatly appreciate it! Ive been doing a lot of research on here, fordification, and just google search too but cant find very much. I know ford used two different types back then and mine is the one that lays side ways with the valves pointing towards the driver side fender. Ive attached pictures so everyone can see what Im working with. Also, the last picture, there is a ground wire with a plug in male type of connector and the female side I have it plugged into might not be right, but it was the only thing laying around not plugged into anything. Thanks for taking a look!

Ground Wire?

 

IMO this is the best time to upgrade to a modern style Sanden unit. They are more efficient and take up less room in the engine compartment. I think they look better too.

With regard to your unit, that wire is not a ground wire. Typically it is routed to a pressure switch on the dryer canister and then through the firewall to the evaporator unit. The evaporator unit energizes that wire to tell the clutch to engage and disengage as appropriate.

Unfortunately I don't have pictures of an old style set up like yours, only a newer style setup.

Good luck with the project!!

 

My 69 has the upright mounted compressor but maybe the pics will help some. Glad you're keeping it original. The aftermarket Sanden type compressors won't last 50 years like these old units.

 

1) Factory installed integral A/C is combined with the heater. The A/C controls are in the same panel as the heater controls.

2) Deluxe dealer installed A/C is not combined with the heater. The two A/C switches are located in the bezel that extends across the entire underside of the dash.

3) Economy dealer installed A/C is not combined with the heater. The two A/C switches are located in the bezel, that's located at the center below the dash.

 

 

Beautiful job Mach428, that's my kind of restoration. I'll be referring to your photos during the restoration of my 69 F-250. I'd love to see more photos of your rig.

 

 

 

 

Pic = 1968/72 F100/350 with factory installed integral A/C: The A/C's expansion valve is located behind the glove box, so it has a short liner.

There is another glove box located within the bezel.

 

No. That is the power wire that energizes the clutch. Ground is through the compressor, brackets, then engine.
