Save all the dialect and go to the 67 Electrical Assy manual, page 54 (E7-8617-1)

Whoever says there are no Ford drawings in the 67 assembly manual for the Tach type alternator (and cluster) could be incorrect.

Ok, I guess I didn't expect to find the correct picture 20 pages later!

Thanks!

196667Bob -- I think I fixed my reply 41 to read better.

It may be that early non-tach cars had the 2 boots (BAT and FLD) and later had the 1 piece connector with caps. Perhaps the latest 1 piece connector version is what is shown on page 33 of the Electrical Assembly Manual after it superseded the boot vertsion.
Page 54 shows only the Tach alternator wiring and 3 boots -- it does not show a 1 piece connector version.
Makes me wonder if a 1 piece (BAT and FLD) connector with a lone STA wire even exists?

I believe it must be in late 67 production that the individual boots changed because every 67 Shelby that I have observed over the passed 40 + years that still had original wiring had the individual boots. That would seem to indicate the changed happened at least on SJ cars sometime in July 67 or after.

Bob : This is good to know. It just shows another case where one cannot go by the dates on "superseded drawings" as being when they were actually put into effect. In this case, the date on the AM drawing (E7-8601-2) of 10/14/66, which shows the one piece rubber connector, clearly does not indicate that this change was made then, but at least after July of 1967, and possibly not until the 1968 Models. This same occurrence also seems to be the case in regard to the 1967 Low Fuel Proof Wire for the Safety Convenience system, which is shown on AM drawing E7-8618-3, dated 1/16/67, as going from the firewall, along the RH , firewall to fender support, and then to the starter solenoid. While the 68 Models did follow this routing, at least so far, we have no confirmation that 1967's after 1/16/67 had this routing.

Richard : Yes, I am the "whoever" (where is that foot in mouth emoji), as while I did look a few pages before and after page 33, I, like Bill, never thought to look 21 pages ahead !  Good find.

Bill : Yes, both John's and my original harnesses had the two boos plus a sinle wire with no boot for the stator.
As far as a single rubber two connector harness with a separate non-booted wire for the stator, I believe that that harness was what started me on this thread. I found a NOS C7ZZ-14305-B harness (pictures attached - you'll need to zoom in on the harness) was nothing like my original. It is my belief that it is a later Service Replacement harness, which was also used for 68's which is why we find this is what the Mustang Suppliers are getting from their Vendors.  Which is why I had to end up having mine "custom made".

Thanks for bringing this back to "light" to add more "fuel to the fire".

No problem. I added "tabs" to some of the manuals to find such things easier

Just when you thought it was safe to go into the water (don't grab the alternator output!)...

I found either a very late 67 or a 68 Tach harness. To compare, I've added the two pics here in the same same orientation.
First is my March 67.
Second is the late 67 (I believe, since I have never parted out a 68). If this is a 68 let me know ...

Most interesting to me is the third picture.
The round battery output end that normally goes to the starter solenoid (on Shelby it goes to a special insulated post for the ammeter) on the early harness (right) is not remotely the same as the later end (left).
The repops all --so far in my searches -- have the square rubber battery end but with early round boots!

My take is that even though my original harness needs help I may have to take the time to restore it rather than use the EASILY visibly incorrect repop -- which I gather would lose me points in concours.

Reusing the original vs using the repro is a personal decision that you will have to make. If you can make the original harness to look ads good as new then there will be no deduction however if the wiring shows age that might offset any advantage you might get over the repro. In MCA trailered concours or SAAC DIV II concours there is no deduction for "good" reproduction parts  The repro harness may or may not receive a deduction depending on the judges, how much it stands out and or how far off the plug ends compared to genuine. FYI make sure you get the small block harness vs BB one.  The difference is the ground terminal is larger diameter for the larger ground bolt on the BB.

Thanks for your insight, Bob.
It's all about choices, isn't it?

I'd like to also thank the other Bob (196667Bob) for his email making me really look at my routing and find that I had the field wire and stator installed visa-versa. A real Doh moment.
My stator wire is still too short due to a repair, but he has me thinking about other options.
Thanks Bob.

I had a custom wire assy done for my tach alternator set-up and I'm quite pleased.
My battery output wire is rounded like my original and the rest looks very nice!

Looks good .I would cut the sheath on the block ground end off. They were more typically not covered like the alternator end ground.  Just what I have seen. Where did you get that harness?
