Dash wiring questions.

As I'm getting into the dissection of my '66 F-250, I'm running into a few more mysteries that maybe someone can shed some light on. One is the momentary switch on the dash, just like a door jam switch. It appears to be period correct with no noticeable alteration to the wiring. Any guess as to its purpose? Also, another "turn/pull" switch just to the right of the steering column, next to the choke. A large flasher unit shares the wiring (appearing original) which is soldered to this switch, but there is also the original flasher unit mounted behind the instrument cluster. The bezel (original also) which trims this switch on the dash is blank. Is this for a trailer harness or camper?? Any other ideas? Thanks...see photos.

Dash wiring

The push button is for the windshield washer and the push/pull button is for an emergency flasher.

Thanks a lot for your information. It will help me check the integrity of the original loom.

Dash wiring

You are welcome. I am right now in the middle of reinstalling the custom cab wiring harness in my 65 crew cab. I have been doing a lot of research and looking at wiring diagrams. Ask if you need more info.

2C-11500 .. Windshield Washer Switch (Motorcraft SW-287) / Obsolete

1965 F100/250 with single or 2 speed wipers / 1966 F100/250 with single speed wipers / 1966 F100/250 with two speed wipers before serial number 760,001.

Originally this switch was used as the starter button on 1952 trucks!

With 4 way emergency flashers, there are TWO flashers behind the dash, one for the turn signals, t'other for the 4 ways.

Both flashers have two prongs and look identical, but the 4 way flasher is a H/D unit, as it has a louder CLICK.

Thanks for the details. It's amazing, referring to the technology of the era that, during an emergency, you would have to be together enough to operate the 4-way flasher switch. If anyone is looking you can still find those pushbutton switches for both Ford and Chevrolet cars of the 50's. Some have spade terminals and some have sockets like the one depicted.

How many would'ja like? 2C-11500 ~ Green Sales has 2 & Carpenter has 1,426!
Look at the bright side, at least the 4 way switch is EZ to access.

1967/69 F100/350's have the 4 way switch mounted to a bracket on the inside of the glove box!

So, I have seen an emergency flasher "jewel" indicator lamp in the parts catalogs. Is that something my '66 may have had, or is for other years? I'll have a blank space where the dash controls reside, as I'll be abandoning the dash-mounted choke control. The indicator lamp would look cool next to the flasher switch.

Dash jewel

I put the dash jewel in place of the choke cable, just like you are thinking. Be aware you will have to enlarge the hole. FYI
I think it looks good there.

Thanks for the advice. I do think it makes sense to indicate the purpose of the E-flasher. Did you solder the wiring to the 4-way switch or splice into the wiring?
Thanks again for your input!

Looking at the diagram more closely, I see two leads with sockets on the flasher leg. I'm going to guess these would be for an indicator lamp!
