Your own personal EVTM is always handy too.

A fuse panel cover is SUCH an easy pick at the breakers.

Yes!  I have the EVTM's from 1980 - '87, and then again '96 lined up in the bookshelf above the computer in the shop.  It is lots faster to pull one out and look at a page than to go to where I know it is on the site.  

[Clex]

Awesome thanks for help everyone, after looking at the EVTM I'm going to try and find a personal copy of one Id love to have that book in front of me. Yeah I'll be going to the breakers here shortly again so I'm sure we will find a cover with ease.

Edit : Should I just go ahead and grab a 1980 version or does the 1981 cover the same stuff?

[salans7]

1980 was an introductory year for these trucks, and things that went wrong in 1980 were updated in 1981. So you may find quite a few differences between the two, and in that case I would probably shoot for a 1980 EVTM.

[Gary Lewis]

Yes, go with the '80 EVTM. The '81 EVTM will be maybe 98% correct for the '80 trucks, but there are are differences.  One area for differences is the warning light wiring.

But, there were changes during the 1980 model year, so depending on when your truck was built you may find that the 1980 EVTM is correct or maybe the 1981 is correct.  So if you have the 1980 EVTM and find it doesn't match yours then use the 1981 version on this site.

[Clex]

Perfect thank you guys for the heads up on that!

So I'm looking to get a new distributor cap and rotor, ignition coil, new spark plugs and spark plug wires and anything else that I may be missing for the ignition to get this truck to hopefully run correctly. Was starting to look online and kinda confused on how to identify which stuff I need like for example the cap/rotor some come with duraspark 1 or 2, I have no idea at the moment how to check what version it would be. Been looking through the website on different stuff just not 100% if I'm in the right direction. I have been going to auto stores around here quite a bit but I've yet to get someone that seems to know what is going on and getting correct parts and get me steered in the right direction on this.

[ArdWrknTrk]

Look at the module on the drivers side inner fender.
How many plugs does it have?
What color is the plastic where the wires enter the aluminum?

If you answer 2 and Blue, it is DSII.

Pretty simple really.

[Gary Lewis]

Right, Jim.  But, I'm pretty sure the 400 never came with anything but DS-II.  I'm not 100% on that because it was used through 1982 and some funky stuff was trickling in that year.  However, since the 400 wasn't available in the lighter trucks, I'm reasonably sure 400 means DS-II.

How should I have replied?

[Gary Lewis]

You replied correctly.  I'm just providing background info on why I'm pretty sure he'll say "Yep, 2 plugs and a blue grommet."

Had it been a Windsor it would probably have had 3 plugs and a brown grommet, although that varied by location and application.

[Clex]

Long time away, figured I'd give an update since life has been a wild ride for me.

Finally got around to getting back into the this truck this summer, ended up doing the entire brake system with new everything, including wheel bearings since it all had to come off anyways. Learned a lot I'm pretty fluent in these brakes now so that's a huge plus. Just got it off the jack stands this past weekend.



Moving onto a good tune up, new plugs, wires, coil, cap/rotor etc. parts should be arriving hopefully this week for the long weekend. (Especially since I tried taking off one of the plug wires off and it disintegrated in my hands)

Also working on replacing the old vacuum lines and making sure everything is in order for smog since I'm located in CA. Bit of a rats nest going on with the vacuum but almost everything seems to be in place other then the AIR BPV and possibly the SA-FV (not sure what these are supposed to look like at the moment) Also still have the yellow sticker on the left cover so I need to figure out how to decode that for whatever it represents.

The yellow sticker on the valve cover has the ewissions calibration data.

With that, we can provide specifics about levels and exact part numbers .

Perhaps you'll find this manual helpful?  https://www.garysgaragemahal.com/understanding-emissions-controls.html

ISWYDT, Jim.  

From the two labels I can see that the calibration must be 9-73J-R12, and that agrees with the first snippet from the MPC.  Which then leads us to Parts List #56, which is shown in the 2nd snippet.

[Clex]

Thanks guys! I got some reading and verifying to do now

[85lebaront2]

Unfortunately, my AllData only goes back to 1982, so I can't even give you a diagram.

[Clex]

Its a shame it doesn't go back past 1982, no worries though.

Had a question for this parts list sheet, when it refers to part numbers and gives the number, on some underneath it has a * for example "D8BZ 9B289-B *CX-291" what are they referencing to with those numbers.

Another question is the descriptions for parts they have different numbers, are they referring to parts interchangeable for the application described or the part number section is what ford used to order and the actual number on the part would be what is in the description?

*Edit* Also between my vacuum hose diagram and the calibration page I'm looking at two intertwined things such as the AIR BPV is shown on my vacuum diagram and the calibration page but the Thermactor(Smog Pump?) is on the calibration page but not on my vacuum diagram. I was going off just the vacuum diagram which doesn't show it but now cross referencing with this calibration page its calling for the Thermactor. Figured I was lucky on having non catalyst not having to do as much for this. I have to read up on that emissions book and go down to a wrecking yard

[ArdWrknTrk]

*CX-291 would be the Motorcraft number.

Same exact part, just that you could get a Motorcraft part at a parts store, not only the dealer.
99% of the time the Ford dealer is stocking Motorcraft, but it doesn't fit with the Ford convention of decade, year, division, group, basic number & engineering revision.

And there's no need to look in the MPC to decipher an engineering number found ON a part into an ACTUAL part number that can be bought or ordered.
A Motorcraft number is the same. On the box. On the part itself. In the catalog. On the invoice....

Right. The description is the number found ON a part (AKA engineering number) but you can't order that #, because it isn't a PART number!  .  

The pump itself isn't controlled by vacuum, so it isn't in the vacuum diagram.
The thermactor pump feeds the bypass valve, and the bypass valve is switched by vacuum, so it shows in the diagram.
Just like the air cleaner itself isn't shown, but the cold weather modulator and the vacuum motor in the snorkel are on the diagram.
You need a pump that has 'X' attachment configuration, and moves 'Y' amount of air per revolution, so the calibration table (56) lists the specific pump you need.
But it's not a source of vacuum, controlling vacuum, or operated BY vacuum....

This may be confusing, but I hope it helps.

[Clex]

Thanks a ton Jim, clears some fuzzy areas that I'm learning. This entire thing is confusing to me but it's getting me in the right direction 👍
