Rembrant Posted March 19, 2020 Author Share Posted March 19, 2020 So I finally picked up a whole car load of stuff tonight. Mostly the final pieces for a full factory AC conversion. The dash is in really nice condition, but the steel frame needs some repair work on the driver's side. I didn't need the cluster or bezels, but they came with the whole thing anyway. So now I have just about everything, all removed from three different trucks. Dash/interior parts and all ducts/heater/AC box removed from a 1986. All engine bay lines, condenser, and wiring harness removed from a 1983, and compressor and brackets removed from a 1985 w/302 out in ND. Couple little trinkets I still need, and I believe some misc parts that Shaun may still have, and I'm good to go here. It won't be happening right away, but perhaps I'll start a new thread later on about the conversion. Thanks to all that have helped me get this far. Your patience has been appreciated. Ok, I've been taking stuff apart and cleaning this evening trying to see what parts I'm going to need, and what parts I need to fix. So now I have a few more questions: 1. Where do you buy the little vacuum cylinders? The one I'm going to need for sure is the one for the recirc door (The vacuum motor in the engine bay on top of the heat/AC box). 2. Can the recirc door be removed and recovered? Has anybody done this before? 3. Does anybody know if the bearing can be replaced in the idler/tensioner pulley for the compressor V-belt? 4. Can anybody take a picture of the plugs/wiring in and around the resistor pack in the heat/AC box? I have the wiring pretty much sorted out (I think), but just curious where a couple of the wires go that in near/between the resistor pack and the plug on the AC pressure switch. Edit: 5. Did the trucks with factory AC have different radiator fans? I mean different than the one that is currently on my non-AC truck? Link to comment Share on other sites More sharing options...

YH-362.Mine had a rusted hole in the bottom and I didn't readily find any online so I pulled a nice one off a jy truck. I did find some later year 1 port ones that might fit or be made to fit. Planning to head to the jy tomorrow to pull a couple connectors so can keep an eye out for a good one in case you don't have any luck. 2. Yes, well removed at least. I pulled mine out to powdercoat the rod. It isn't terrible to get out and in although took a little work to get the rod back into the clip on the door. Not sure about recovering it though. That one is thick (hence why the mice go to town on them) so wouldn't be as easy as putting foam tape on it like the other doors. 3. - 4. Definitely can tomorrow if someone doesn't have one handy 5. - Link to comment Share on other sites More sharing options...

Rembrant Posted March 20, 2020 Author Share Posted March 20, 2020 Let's see if this helps: Gary, as Peter Griffin once said, you are as cool as the other side of the pillow! Thank you sir, that picture is exactly what I needed. One of the connectors was broken off, and it wasn't clear to me what it was supposed to be attached to, but now it is. The wiring for the AC is really quite simple, so this is going to be a pretty easy install. A lot of time, yes,...but not difficult. The picture below are the two wires/connectors that I cut from the harness of the donor truck. These should be connectors C606 and C606A, and if I'm understanding the wiring correctly, these same two connectors should also be in my Non-AC equipped F150. Would you agree with that thought? The only other stray if this one wire off the AC harness closer to the plug for the AC compressor clutch. It must be for the throttle kicker, which I hadn't planned on using. I might just delete that wire...it's burned and melted anyway. Link to comment Share on other sites More sharing options...

Looking at the 1984 EVTM (your pic is a bit small) I agree that C606 should be in the truck if it is non-AC, and C606A will be there if it is an AC truck. Both are gray and have a single pin, and connect BR/O wires. So, you should be good to go. And that should be the throttle kicker, but if your idle is adequate you probably won't need it.
