Topic: Fog Light Switch

[dkknab]

I could not find much about the switch attachment to the under side of the dash panel so I thought I'd share what I have looking for any thoughts.

Apparently there are  pan head screws that attach the fog light switch to the dash. I've ordered some from NPD but that is not what I have at all.

In my case, instead of two screws I only need one screw and mine is a hex head dichromate screw that is screwed into a metal piece instead of a nut as is shown in the assembly manual. I am guess there must have been a change along the line that was not completely documented in the assembly manual. Thoughts?

Hi Jim, not sure what you mean. To elaborate what I see, on page 53 of Electrical Assembly Manual, the picture shows a screw and nut item nr 5 attaching the switch to the dash board with a second screw and bolt right next to it attaching the wire clip to the dash. On mine there is just the one bolt and fast nut attached to the clip holding it all together.

There must have been a change down the road to eliminate the two phillips head screw bolts and nuts to just the one.

"Ford Car Parts" (aka MPC) can be used as a "sanity check". Look up the illustration and see what part numbers are used as a service replacement. If they are the same as what you have, problem solved. If they are different, how different?

The Assembly Manual only documents and shows what was used on cars built on and after (we don't know for how long)  that page was put into practice on each car plant. They were not designed to document all the changes in that area they focus on for the whole year. Couldn't since none fo them were published at the end of the production year. Believe those records were included in other documents the plants had. 

They can be of great help but without a list for each page with the changes made on each one as well as when each was put into practice it does mean that we have to guess or trust. The pages that Jim included in the Assembly Manuals is only moment in time so yes there could have been a change or many changes and this is why we try and dig deeper or maybe the better term would be wider by looking at as many unrestored to help us with the answers we seek. The challenge is that we don't always have enough or many examples and collecting the data/facts on these smaller, least seen details is a challenge. 

Don't recall seeing a picture of that area for a 68 but will make an effort to take a look and will report back if I have something to offer

Thanks Marty.  Looks like you have the pan head screw that seems typical if you order the install kit. Do you have a speed nut or nut with star washer on the other side?

I've ordered the pan head screws and nuts.  When I get them should I replace my hex nut with the pan head nut that seems more correct?

Any others with a 68 Metuchen built car with fog lights who can share a picture of their switch?

Thanks again.

According to my spreadsheet for 67-68 Mustangs based on the "1968 Mustang Electrical Assembly Manual" (AM0023 pg53), one screw 50514-S36 is used to attach the fog lamp switch AND 381726-S100 CLIP to the underside of the dash with nut 34653-S36, and a second screw and nut are used for the same RELOCATED fog lamp wiring clip used WITH the tilt steering wheel.

Upon further review, two screw/nut combinations are used WITHOUT the tilt wheel option. With the tilt wheel option, the wiring is moved to the right and the screw/nut that holds the switch is used, probably for tilt column clearance.
Screw 50514-S36 is 1968 unique, used for the convertible top switch and speed control switch, as well as the one or two for the fog lamps. As it is an 8-32X1/2 machine screw, substitutions are probably easy to find from other assembly line uses. Just don't reference this thread if your 68 Mustang is in the Thoroughbred Class.

And here's the page from the assembly manual.  But it looks like 2 screws are used when swing/tilt column is NOT specified... line 2. Am I reading that correctly?

But is it possible for Metuchen cars,  they installed the switch differently? It seems odd that a previous owner went to the trouble to replace the pan head screw and nut with hex screw and speed nut. Just saying.

In 1968, I have seen the hex head screws with a tinnerman clip on the wiring clip for NJ assy

Read the corrections and comments on my reply number 7 in this thread.

So probably no reason not to use two screws attaching the switch and wire harness instead of the one hex screw I have want to be a bit more correct and at least we can document the intent of the install given the assembly manual.

Agree?

I think I figured out why the change though maybe not documented  well.  I got the 2 screws. It is flippin impossible to install them quickly.  Took me half hour plus and my back is sore plus all the blood raced to my brain.   I can see why they would have changed to the speed nut on one screw instead of 2 screws. Anyone else try to do the installation?
