Topic: Very Early 1967 Wiper Foot Switch?

[midlife]

Today, I refurbished a 1967 non-tach dash harness for my inventory and it was quite unusual---something I haven't seen in about 100 harnesses.  The usual connector for the foot-activated wiper switch was not there; instead, four separate wires in correct colors ended up in molded 90* spade connectors, each with a different color molding.  At first, I thought someone had spliced these in, but I unwrapped the wires and these appeared to be factory correct.  All of the stickers on the harness were long gone.

Is this a very early 67 variant?  Does the switch itself have different colors indicating which molded connector goes where?

I completed a concours restoration on a 67 coupe that had the separate type connectors that you mention. This coupe was a Metuchen built mustang scheduled for build on November 28, 1966. My 67 Metuchen built fastback with a build date of December 10, 1966 had the bakelite or plastic type connector for the wiper/washer switch.

Pete:
Do you remember if the receiver of the wire connectors were color coded to help in connecting them properly?

On the early car harness? Oh yes the 90 degree connectors were color coded as you described.

Thought I'd share a Feb 67 switch connector picture for reference. Especially since it still has a like new part number tag.

Randy, interesting question - I think the folks that replied missed the issue. 

Since there are four individual wires, each capable of being installed on any of four terminals, a classic non-idiot proof situation, is there any help in terms of color coding or labels on the pump (receiver) itself?  If I recall my math correctly, the number of combinations would be four factorial, or 24 total.

Pictured below is a four individual wire pump installed, followed by pictures of the same pump removed on a bench.  I found two other pumps from 67's and they are the same.

I see no indication on how to put the wires back on correctly.  I presume one would have to resort to the manual, a picture, or a hand drawn sketch.

But that does not mean that my pump is original, even though I bought from the original owner in 1980 - anything can happen.

Perhaps someone with a one year 67 MPC can look to see if there were any changes, revisions, etc.

I searched high and low for an early 1967 Cougar harness, I found one. The 4 wire colors are the same early to late, here is a picture showing the individual boot colors.


My wiring diagram only shows the plugversion. I will have my electrical guys map it out tomorrow.

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.

What surprises me is that with all of the 67 harnesses I have in stock and have refurbished (about 120 total), this was the first harness that had the individual wires.  I am pretty sure it was a Mustang and not a Cougar harness.  If the change-over was approximately 1 December, the ratio of early to late would be much higher than I've seen.

I thought I had seen just about everything one can image in these harnesses, but every once in a while I get surprised.  This harness was for my own collection, which I use for measurement purposes when I get a harness that is all cut up and I need to splice in the right length of wiring.  I did splice in a standard connector, however, and saved the connector tips just in case.

The first picture of post #6 with four individual wires is a Dec 15 built Mustang from San Jose.

Interesting, 4 wires, 5 terminals and no color coding. Sure seems like bad way to do things....

Probably recognized by a Ford mechanic at a stealership sometime in late 1966, and the word got back to Ford to implement a multipin connector.

This is the proper placement of the individual wire boots. One of the black wires goes to the wiper switch, the other goes to the wiper motor.

My Sept. 1966 San Jose convertible has the same color-coded wires as shown in Scott's photo.  However, (and to answer one of midlife's original questions) the actual foot switch assembly in my car also had color-coded rivets on the connector prongs as well - see attached photo below...

[rodster]

Interesting....could it be someone at Ford became aware of a problem?

So that piqued my interest even more.

7R02C156 has individual wires, but a pump without color coding (but pump might not be original)

7T01C144 has connectorized wires, but a pump with color coding.  Go figure.
