What the heck is the part the red arrow points at? Been having issues with the turn signals working intermittently and investigated a bit today. It's a small plastic tube with a blue/green wire running to the bottom. Inside the tube was a small brass piece, with about 1/16" of frayed copper wire attached, then a spring similar to what you would find on a ballpoint pen, with the end stretched out.

I am very new to these vehicles but I assume Ford did not fill the hole like this. It would appear that there was a wire attached to the brass piece, which contacts the blue/green wire on the bottom of the tube, but not sure what the other end would go to. The shop manual I have only shows 6 wires from the turn signal switch, I believe I counted 7, and I don't see a blue/green one listed in the diagram.

The diagram I have shows:

blue: switch to flasher
white/blue: switch to front passenger side turn signal/passenger side indicator light
red/black: switch to stop light switch
green/white: switch to front driver side signal/indicator light
green: switch to passenger side rear signal
yellow: switch to driver side rear signal

diagram says horn is blue/yellow, I believe mine is just yellow and I can see it attached to the button (it's not this blue/green one...although I've discovered some pretty stupid hacked up wiring on this truck, so nothing surprises me much anymore)


Thank you in advance for any help.

 

Which T/S Switch does the shop manual represent?

CODZ-13341-A .. T/S Switch = 1961/62 F100/250 2WD

C2TZ-13341-D .. T/S Switch = 1961/64: F100/250 4WD, F350/600, F700/1100 except tractor trailer.

C3TZ-13341-B .. T/S Switch = 1963/64 F100/250 2WD

 

Thank you Bill, I searched some threads a while back regarding the switch and only remember seeing part #'s for the 65/66, and yes, I'm planning on replacing this so that part number definitely will help in my search for a replacement.

 

C3TZ-13341-B = jetcopterpilot contacted me about a year ago...looking for this switch for his 1964, only two were available NOS (now there's only 1).

He did a bit of searching, found out that NPD has it.

 

C3TZ-13341-B 1963/64 F100/250 2WD

Coupla minutes ago, I was trolling thru the 1957/63 catalog looking for pics of clearance lamps...and came across the following pic.

It's not in the 1964/72 catalog.

 

I struck out at NPD, do you have any other suggestions for a source? I read in other turn signal switch threads the recommendation not to replace just the cam (compatibility issues), and not purchasing an aftermarket switch assembly (quality issues)?

 

I believe its called a brush contact. And they are used for the horn. The ball point pen piece you refered to makes contact with the metal plate behind the steering wheel itself. There is another one located on the front of the steering wheel which makes contact with the horn ring when its pressed. I know LMC sells them for around $11.

 

I just got one for my 64 4x4 about 3 weeks ago called allover US located one at mustang parts in LA ND had listed that their were 6 called all of them only one found. paid way to much $$ but now I think there are not many around so up $$ goes

 

But your 4WD uses a different switch than the OP's 2WD / The switch you bought is C2TZ-13341-D (from Mustang's etc in Van Nuys CA).

I know this because I gave you the info when you sent me a P/M asking for it.

The OP needs C3TZ-13341-B .. 1963/64 F100/250 2WD / Obsolete ~ ONE available NOS

C2OZ-13A821-A .. Horn Brush & insulator Kit / Trucks: Use with 3 spoke steering wheel / Obsolete-Reproduced

Applications: 1961/66 F100/250 2WD / 1966 F100 4WD / 1967/70 F100/250 2WD/4WD & F350 // 1960/64 Galaxie/Falcon/Comet / 1962/64 Fairlane / 1965 Mustang w/a Generator.

When the horn ring or horn button is removed, these parts are located within a hole on the outside of the steering wheel. The brush contains a copper wire that is notorious for snapping.

People remove the steering wheel, brush falls out unnoticed, then when they re-install, the horn no longer blows and they wonder why.
