Part Identification - What are these?

[Jordanlogo]

Anyone know what these are?

[Jordanlogo]

Also, if anyone can link me to a part identification chart of everything under the hood that would be awesome.

Gary, you da man

This illustration from the '81 EVTM shows that that's the MAP sensor and EEC power relay behind the battery.



Single black with light green (#4) seems to be C105, at the ignition module.



I'm thinking #5 is your horn relay. Although the '81 EVTM says it is mounted to the speed control amplifier...

[Gary Lewis]

I think #5 is a trailer relay.  It isn't shown in the '81 EVTM so it may be an '82 and later thing.  But this is how it is shown in the '85 EVTM:




But, the thing next to it on the left is probably the auxiliary battery relay.  Do you have an aux battery?

As for an page on everything under the hood, we don't have one.  There are soooooo many different options depending on the year, the engine, which carb or EFI, and then if it is a CA/49-State/Canada truck that it would be next to impossible to create that page.

Interesting thread - I don't have some of these parts under my hood.  Kinda afraid to ask questions or look too far.  Truck runs 98% great and don't want to mess with that.   I think all of my emissions stuff is gone.  Just old school carbureted 302 with aftermarket one wire electronic ignition.   NC doesn't require any sort of inspections after 35 years old.  Not even a safety inspection!  Scary to think about sometimes.

My truck does appear to have some speed control stuff under hood, but steering wheel is non cruise.  Cable broken/cut at end of vacuum thing.  

So I'm useless on this thread other than learning what some of the unidentified stuff is.

You apparently have the EEC-III system, your distributor may have a strange cap and even stranger rotor. Look under the driver's side of the seat, there should be a computer under there.

[ArdWrknTrk]

It's a Cali truck.
I assume it has a VV carb too.

I wonder if that odd flat connector is the diagnostic or programming plug I've heard about but never seen?  (I'm a long way from California!  😉)

Gary, numerous times I too thought how beneficial a page like this would be.

The members (and visitors) to this site possess a wealth of knowledge that collectively is unavailable anywhere else. I think it would be an absolute boon to your site if we pitch in and contribute with identifying each part.

Using the engine compartment as an example, ideally a photo of the engine compartment has clickable areas (using coordinates) allowing the user to zoom in to a specific area and drill down to the part. Agreed the multiple combinations of engine/trans/accessories etc. is complicated, but identifying the components could be possible, whether someone has the component or not. All we have to do is start.

To make this efficient, stick to the facts of the object e.g. part number, location, function, and perhaps what connects to it, what it connects to, where to find relevant information in the relevant EVTM (year). No superfluous text or photos are necessary, and standardize the text-based description and how photos are taken/presented e.g. quality of the photo (orientation, lighting) and size when uploading.

Maybe something like-
















Location: Firewall, top middle
Item description (per the MPC, but include aka names for the item): Motor Assembly (Windshield Wiper), aka Wiper Motor
Core part number: 17508
80/82 F-U100/350 Before 1/82 - E0TZ17508B r/b E2TZ17508A
82/86 F-U100/350 From 1/82 - E2TZ17508A

No small undertaking for sure, but worth considering?

[Jordanlogo]

That idea is awesome!

[Gary Lewis]

Would something like this work? You can click on the blue box to be taken to info about that item.

This is from our page at Documentation/Interior/Interior Trim and then the Bronco tab as the Regular Cab tab appears to be broken. Anyway, is something like that what you had in mind?

[Vic Roma]

I think so.

[Vic Roma]

A real-world example would help too.

The photo of the part on the physical truck could be necessary as parts change over the years, either from the factory or previous owners, or the part could be missing and real-world photo would show the surrounding area.

All this *in addition* to the MPC picture.

Now you are getting into the complexity thereof.  Each year is different; each engine w/in the year is different and some years have two different engines, like the 302 carb'd and EFI'd and the 351W w/a 2bbl and 4bbl; two different GVWR's - above and below 8500; and then there are at least three versions - California, 49-state, and Canada.  And that is assuming there aren't differences between manual and auto transmissions, and there are.

So, 7 years, 10 different engines, 2 different GVWR's, and 3 different government emission standards.  At first blush you are talking 420 different combinations w/o the transmission difference.  But it isn't quite that bad since not all of the 10 different engines were offered across the 7 years, but there are still a huge number of combinations.

I'm not saying no, but I'm asking if we can't just answer the questions one-off as we go rather than trying to answer all of them up front?  

Am I thinking incorrectly?

Yes, I actually do. I don’t run a battery in the tray, but it’s there 

[ArdWrknTrk]

I looked and looked at the towing and trailer diagrams in '81.....  

But the only relay I could find close to there was the speed control horn relay.

I knew the heavy duty one was the auxiliary battery relay.
But Jordan didn't ask, so I didn't bother posting that diagram.  

[Vic Roma]

In short, yes.

In long, you beat me to it. Since the suggestion will take a long time to execute, especially since we don’t have a full-time team of researchers and programmers to do the tedious work.

Still, this information needs to be organized. An alternative suggestion is to create a dedicated folder entitled “What is this part (WITP)” or something to the effect. Then inside this folder create a form that requires the user to standardize the question using keywords and phrases. The folder either functions as one long page of new topics, or you could break it down into sub folders with headings such as engine, transmission, axles, etc.

Either way, the posts would be searchable based on a standardized title format e.g.  using the post that was referenced further up this message chain, the entry would appear as “Engine Bay, relay” then follow up with a clear “medium” sized photo, “float left” so it looks presentable, etc.

Then those who know reply with the detailed description.

That way, as you wrote, everyone answers only the questions asked.

[Gary Lewis]

Jim - Yes, apparently that wasn't an option in '81.  But I recognized it from Big Blue so looked at the '85 EVTM.

Jordan - Make sure you don't have the positive aux battery cable floating around as it'll be hot when the key is turned on.

And now we see one of those elusive options that it would be good to be able to ID.  Maybe I can pull pages from several EVTMs to get a start?

[Vic Roma]

And pin at the top a folder containing detailed information on  “how to use this (form/page/section)”. The aim is to help standardize how to ask the question/present the information.

[Gary Lewis]

Vic - I think I like this approach, but confess I don't fully understand it.  Could you explain again?  Or provide an example?

[ArdWrknTrk]

I think Vic's volunteered to re-write the FSM drawings and descriptions, then do all the links in the background for you Gary!
