Topic: Very Early 1967 Wiper Foot Switch?

[priceless]

Here's my Oct. '66 NJ built '67 coupe. Car was painted back in 1998, so you'll see paint on the wires. From my knowledge, this is the original foot pump. My (late) father in law bought the '67 in 1979 from the original owner.

Here is a 11-04-66 SJ 67 with the early wiring. Lets try to figure out when the change over happened.

Now I am looking into this tonight! I'll guess first, then update with fact. Mine should then be an "individual wire" design too.
It is very possible that the other options might factor in on the exact change over date (with tach vs. w/o tach or with AC vs. w/o AC?)

sheese! ...yet another 1967 anomaly!!! ...wth Ford? How much planning did you (engineers) really do before going to production??? lol!

I would suggest the early style as you mentioned.  A/C has no effect since the wire harness is completely separate.  Not sure about tach, but suspect no effect.  Do you need the harness?

Do you need the harness?

I sure hope not! I'll be pulling it out within a few weeks. The car is coming apart this weekend (engine, trans, fenders & doors) and will be up on the twirler (I hope) within 2 weeks. My plans were if there were any problems with my wiring, I'd be calling the "Pink Flamingo" aka Midlife to fix it.

I've been called many things in the past, but "Pink Flamingo" is a new one!

I prefer Mid...easy to remember.

OK

Hmmmm... Build date 11/2 doesn't seem right, but I know it is original.

Some updated information.  In a previous post I see a picture with part number C7ZB-17664-B, so I took at look at a few MPCs, picture attached.  Also I checked the one from my car, and it is a -B as well.

In the January 1967 version, there is a note that says C7ZB-17664-A is what C7ZZ-17664-A is marked as.  This same note continues in the August 67 version and is carried on to 1975 as well.   There is no -B reference.   The MPC is simply a reference point, not gospel.  The first picture shows all three MPC versions.

Since we were on the discussion on wiring changes - from individualized color coded plugs to a single connector assembly, I did some digging there.  The connection to the W/S washer pump is on harness 14401.  In looking at the shop manual, figure 34 shows the later single connector style, which makes sense.  Refer to attached picture 4.  The MPC lists four different applications - with and without the GT equipment group option (fog lamp), and with and without tach.  The 67 MPC lists four part numbers.  The 68 MPC takes the four part numbers through two changes, dated 1/3/67 and 4/15/67, resulting in 12 different part numbers.  Refer to pictures 2 and 3. Picture 3 is a table I created which is intended to make it easier to follow the changes.

Based on this alone, my guess is that the 1/3/67 change instituted the single connector replacing the individualized plugs.  That is based solely on the information described above, and is a starting point for discussion. As always original unrestored cars are needed to validate or correct these assumptions, but it is an area difficult to get a camera on.

Richard's car, built before mine, has the single connector.  Mine has individual plug in connectors.  Both are SJ cars.

Also on the topic of 14401, my GTA has a single gray wire in parallel with the wrapped harness, but not part of it.  I don't see why, then, the MPC would list a different 14401 between non-GT and GT, at least for before 1/3/67.

The answer perhaps is that there was a whole lot of change going on, and it was not worth chasing every last change with MPC revisions.  Mechanics can adapt at the point of installation.

The easiest answer is this is a Supplier Issue.
Marty's 11/4/66 built SJ convertible example has the individual wires with the colored identifier ends and Marty's example is equipped with almost same list of factory options as my 11/2/66 built SJ example, (excepting the Convertible option). My example does have the colored rivets on the pump but nonetheless, has the single plastic connector on the harness.

We already know that Ford used multiple suppliers to build these harnesses. Perhaps some of those suppliers did not have the connector 'in stock' earlier on in the year.

[67gta289]

That is a solid potential.  If that as the case I would say that there is no correlation between the pump assembly and wire harness, and any combination would have been possible.  Also then the  nominal 1/3/67 harness revision would have had one or more different changes that were the basis for the rev.

I have a late Nov Shelby. The tach harness is original to the vehicle and it is a single connector.

Excellent.  The two black wires are the most confusing: one goes to the wiper switch itself and the other goes to the connector to the wiper motor.

I wonder if these two black wires, if they we're inserted incorrectly into the pump switch plastic connector, if it might prevent the pump switch from activating the motor like it is supposed to.

According to the factory schematic illustration shared earlier and a harness I have on hand, circuit illustrated as circuit #28 Black wire (not #28a) is connected between the two hard plastic connectors of the two switches and on the PUMP connector, circuit #28 is inserted into the hard plastic connector OPPOSITE of the white wire. If I haven't lost you, if you look at the 2nd image supplied below, the black wire at my index finger is the black wire (circuit #28a) that runs to the WIPER MOTOR.

Again, I do not know if by chance the two black wires are connected "reversed" would prevent the washer pump from activating the motor or not (I did not reverse engineer that aspect) BUT I imagine it COULD happen and therefore MAY be an issue.

ALSO: FWIW, the instrument panel wiper switch connector view (or the Ford schematic previously posted) seems to be confusing because the illustration seems to show the wires coming out the face-side of that illustrated connector but the factory harness I have, it is evident the wires all come out the back-side of what that Ford illustration seems to show. Look at attached images for clearing these muddy waters and perhaps you see what I am trying to convey.  (NOTE: first image below is the instrument panel mounted wiper switch and the second image below is the firewall mounted washer switch connector).

I think my restoration came out ok.

Thanks for all the pics!

Looks a little on the "semi-flat" side of semi-gloss to me but the label sure looks nice!
