Topic: GT/Deluxe Interior Schematic

[TonyFio]

I'm reinstalling my engine compartment and dash wiring harnesses and am finding that they are quite different from schematics that I have (65 and 66 colorized) or have found online.

I have the deluxe interior and based on:
https://www.concoursmustang.com/forum/index.php?topic=7784.0
the dash harness (at least) is different from the standard models (ammeter related for one).

Does anyone own and know if either of the following at NPD include the GT/Deluxe interior schematics for the 65?

Documentation for the mid-year 65 entry for the GT and PonyCar Interior (each have the same underdash harness and nearly the same headlight harness, although the foglamp may be missing for the PonyCar) is somewhat scarce and incomplete.  Making matters worse is that there is an early and late standard 65 wiring set, the latter introduced at about the same time as the GT.  Thus, the 65 model year (excluding the 64.5 version) has 3 different wiring configurations.  Must have driven the beancounters nuts!

If you have particular questions, I can be contacted via phone or e-mail to help answer your questions.

Yikes! At least I'm not going nuts. When I saw wire colors on schematics that were nothing like what I have, it really had me scratching my head. I'll try to document what I think is correct and then pass it by you. If you concur, I could post it here for others. It just may take awhile.

Consider this.

- there is an early and late standard 65 wiring set, the latter introduced at about the same time as the GT.  Thus, the 65 model year (excluding the 64.5 version) has 3 different wiring configurations.  Must have driven the beancounters nuts!

Ford assembly line workers were instructed to put a specific part in a specific place for a specific car - the directions came from a build sheet. If the part was revised, the worker didn't care, see the above. That "quirk" was also build date controlled.
Ford procurement bought parts (cable harnesses) to be delivered weekly (or daily) but certainly not for the entire year all at once. For the "beanies", it was all part of the changing production plan.

Yikes! At least I'm not going nuts. When I saw wire colors on schematics that were nothing like what I have, it really had me scratching my head. I'll try to document what I think is correct and then pass it by you.

The Mustang Assembly Manuals published by Osborn "should" be the latest version (and hopefully the last version) that was used for assembly, which is the reason you don't always find your exact wire colors. It is a problem for you, but not for Ford.
(Note: Osborn Productions has stated they did not get all the 64-73 Mustang documentation, and some of what they got was damaged beyond use.)
One more time, Ford was not building Concourse Grade cars - you are.
(Note: One of my sets of 65 and 66 Mustang Assembly Manuals is marked up with corrections, changes, general notes and personal observations. It's the only paper we have so I use it.)

They are not. Jim collected a fair number of original manuals but they were printed from  many different time periods and most had damaged or unreadable pages due to poor storage conditions over the years so he picked the clearest of each page he could find and included those in what was reproduced and being sold. He had a closest full of these from different years and specific manuals but many had mold and other issues that took out many pages

He did the best he could given how rare the remaining copies were

I believe I said that.

Yes saw that, but I was referring to your comment quoted in you post about the published manuals should be the latest version. Just thought it was in conflict with your words in another part of your post where, like me, make mention that pages were taken from versions published at all different times during the year.

Just wanted to make sure viewers took notice. Of which you have helped with

OK, how about - "latest available now from aftermarket sellers" - which may not be the latest revision used on the assembly line.

It took awhile for me to get this info documented, but I'm about to have a knee replacement and am not allowed to work on the car.
I started with the "GT Only" ignition page of the Osborn wiring diagram manual as that includes the ammeter in the drawing. Changes reflect what I found on my SJ 5/65 Lux coupe (65B). Don't know what is normal for GTs for example, but nowhere have I found documentation showing the BLACK wire from the battery side of the starter solenoid going to the main disconnect and from there to the ammeter and plugging to the BLACK-YELLOW.
In the color code block I added a new color "655A" as BLACK, replacing "655" RED.
I also documented the pin outs for both sides of the main disconnects with as much info on where those wires go as I could figure out.
Hopefully this helps someone with wiring the same as mine.

The ammeter doesn't have actual pins; it is an inductive device, so that the main power line goes through a metal loop which inductively picks up the DC current from the battery.  Your diagram of wiring at the actual ammeter is somewhat ambiguous in that regard.
And yes, Ford wiring documentation is at times somewhat deficient.  If you think this model is bad, try 67/68 with tach dashes.

That is true. The BLACK wire has a female receptacle. The BLACK-YELLOW connects to it. As you said, that circuit passes through the loop of the ammeter. The diagram was taken from the Osborn manual and I didn't modify the ammeter image.

After checking out your web site, it's clear you know a whole lot more about these than I do. If you see any errors in what I posted, please let me know.
