HVAC Control Panel ??

[FuzzFace2]

This HVAC control panel will be the death of me

I have 2 questions

1- what is the vacuum hose pin out of the control? I see you have one listed in the post on "vacuum heater vavle" but they are in line guessing the early control as I was told I have a later one and they are not in line.
Number on valve: Motorcraft E1AH-190961-BA

All the ports are open and are listed L>R as below.
top row right side: 8, 9
1 row down: 3, 1
1 row down: 5
bottom: 2, 7, 6

2- I don't have the temp cable. Is this just for the AC box or can a non-AC cable be used as I have 2 from the 81 non-AC box?
How long is it if I have to make/find one?

On top of all this I may need to remove the dash to do the vacuum lines and the cable.
Thanks for any help you can give.

I should add I don't have any of the colored plastic lines so I am running all new black rubber line so would need to know port # to what vacuum motor.

Dave - I should have an extra vacuum harness. And, I may have the cable as well. It will make things sooooo much easier. I will look this afternoon.

Gary, I thank you that will help a lot. Take your time I am in no rush.

It is one of them things I am thinking of this part and once I know what I am looking for I can keep an eye open for the parts.

It is also hard to hit the junk yards around here because of the hours I work and the hours they are open.
Then they may not even have any thing that old to pick parts from.
I thank you again

Let me know what you need. I can easily get these things at the junkyard. And Gary is right. You really want the OEM vacuum harness with the thick rubber terminals that go on to tha vacuum motors. I think rubber hoses would stretch and leak and fall off after a while. They are conveniently color coded as to what goes where.

I also noticed that the harness mounting posts are broken off of your switch. The harness plug is held on by those awful little sheet metal twist nuts like the turn signal lights and horn pad pieces. I broke both of them on my vacuum switch when I went to switch the harness plug, but luckily there was still enough of a stub that I could just get the nut twisted back on. If you want I could send you a vacuum switch with the harness attached?

And yes, you definitely want the right heater cable that operates smoothly and has the plastic tab that mounts to the heater box. That is what the cable pulls against. That was broken on mine and the PO had a strange wad of rags and duct tape holding/jamming it in place 🙈

Dave I got your PM/e-mail (that's how this forum's PM system works) and I will hold off mailing the plug in in case you need other items I can send them all at once.

Dave - I have a 1985/86 vacuum harness as well as the control cable that you can have.  However, I suggest you read a bit further before deciding.

One reason is that if Jonathan is shipping you the connector already then it might keep the costs down if he were to ship you everything.  But, that means he has to source the parts.

And, then comes the question of what parts.  If I were you I'd seriously consider going with a 1980-84 control.  That's because of what I've just found and will write up on the Vacuum Controlled Heater Control Valve thread ASAP.

Jonathan, Would the 2 studs be the white things on either side of port "5"?
Then both of my vac switches are broken that way and why I did not know.

If you can come up with the colored hose harness & cable and now a good switch let me know how much and where/how to send money.

I guess the switch & harness would match and may not have the ports in the same place, as long as it works.

Gary, Lets see what Jonathan can come up with for the hose harness & cable and the electric plug that goes on the end but will keep you in mind & posted of the out come.

Thank you guys, if you don't know it you are a lot of help and my wife tells my I need help! LOL

Dave - Don't miss that if you use an 85-86 control, like you have, you can't easily do the water shutoff valve.

I did see that that but beggars can’t be choosers when it comes to parts for our trucks.
Also till I know that vacuum switch can be swapped to the control I might be stuck with what I have as I also have duel tank panel with AC.

I could also go with a manual valve if I was that worried.
I also have the 300 using EFI manifolds and the heater water will also be used to heat the intake manifold.

Dave, if you use one of the Chrysler ones, they do provide a circulating loop when "off" so you can close it and still have manifold heat.

Yes, that's exactly right. Let me see what I can come up with. A 85/86 switch with a vacuum harness plus the plug that I already got would put you in business with your current controller. But would you prefer a 1980-1984 controller with harness and pigtail? I got that you need AC and dual tank switch which is how most of them are on Arizona trucks. I am probably going back to the junkyard on Wednesday.

Jonathan, I will leave it up to you on what you can find.

just a recap:
85/86 pigtail, guess a good vacuum valve switch but I think I can come up with something to hold the hose manifold in place, hose manifold, temp cable.

80-84 control panel for factory AC and duel tanks, pigtail, hose manifold, temp cable.

One of the reasons it was brought up on using the earlier one is for adding a vacuum valve to the heater hose to help the AC work better. But it was also posted you can get a different valve to do the some with either system.

Think that should cover it. Again what ever is easier to find and pull from the JY.
PM me when you have everything to work out payment.
Thanks

Dave - I'm not sure what post you are talking about, but I don't believe it will be easy to use the 85/86 controls and turn off the water in both Vent and Max.  Yes, you can do it in Max because you can tee into the Recirc door's vacuum, but that won't turn off the water in Vent.

Or, you can use a manual valve.  Or, an electric valve.  

If that's adequate for you, then carry on.  I'm just wanting to make sure you know the situation.

Had a big thing typed out on my phone and lost it :(

Yes I under stand about the controls and vslves.
