Let's try this diagram from the Jim Osborn Reproductions 1966 Ford Truck Wiring Diagram Manual. I went out and looked at my truck. There is a four wire black plastic gang plug which plugs into the voltage regulator which includes the green/red wire. Of course it disappears into a wrapped bundle that I don't want to unwrap, so you'll just have to use this picture. The wire number is 904. It shows a break at the firewall main disconnect. I think this should do it for you. Good luck.
Thanks SS, I have the Jim Osbourne reproduction wiring diagram, and with regards to the Custom cab auxiliary gauges, it's useless.
As an aerospace engineer, I think it is appalling. It depicts some but not all disconnects, it doesn't have separate drawings for the different options. It implies that what is installed on an F600 is the same as an F100. It's better than nothing, but I'm really hoping the shop manuals are much better.
I'm sure I can make the gauges work, and when the harness shows up I'll be able to do a better job of sorting out what connection goes where.
I talked to the fine folks at Narrangansett Reproductions and found out that the 904 green/red wire in the 10A655 harness is not used in my truck since it came equipped with the alternator light wiring as part of the 14401(?) headlight harness.
Also, although it isn't listed in their on-line catalog, the 10A655 harness (ammeter and oil pressure gauge) is available in reproduction as part number C666613.
One of the oil bath breathers I recovered from the Utah F250 was stamped as shown below.
When I tried to clean it off with just water and a little dish detergent it started to smear so I stopped. I would love to get a stamp made but I don't know what I would have to do to get a license from Ford.
Interesting. I guess the -R is probably for a straight 6 whereas the -Y is for the V8. But I would also imagine they would have both been stamped rather than one use a decal.
The -Y is purely a coincidence and doesn't have anything to do with a Y in the VIN meaning 352 in 1966. Same letter of the alphabet, but no correlation in this case.
The actual part number for this filter is
C3TZ-9600-AA
Identified C6TF-9600-T,S,Y,Z - any of the letters are valid for this ID.
You can see the stamping and the separate decals in this close up of an engine still on the assembly line in 1966 model year.
Also, have you ever had a chance to compare these 1966 4x2 oil bath air cleaners to the 1966 4x4 oil bath air cleaners. Anyone know what is different? It's pretty interesting.
Here's another with ID number C5TF-9600-F. I won't go into the details of this one, but used with C and N-series. Another example of the ink stamping and how it only varied slightly from model to model.
Wow, that's just crazy having so many different ID numbers and then not even being the same as the part numbers. Visually at least they all look the same to me.
A stamp would be great. Would be trick to make it so that the number could be swapped so the stamp would be universal, not that it would matter for a one time use.
They visually varied some. These two are of the "closed system" style where the snorkle is connected to the oil fill cap, which is a different style also than on the "open system"
Here's two "open system" style, with a 2WD like yours on the right and the 1966 4WD for 8-Cylinder 352 on the left. Instead of the top fitting over the bottom like you might be used to, this one the bottom is more exposed and the top nests down inside of the bottom. The decals and ink stamping are actually on the outside of the BOTTOM piece, rather than the TOP piece like yours.
The one on the left is part number C6TZ-9600-E
Identification number C6TF-9600-D,E
Here's the same one on the left as above, but on the right is the one for 1966 4WD with 6-Cylinder 240/300. Base is different since it is a 1V carb, but the top is the same.
Part number is C6TZ-9600-C
Identification numbers C6TF-9600-A,C,L,N
LOTS of variations across all of the oil baths they made. This is just truck and what applied to 1966 F250 (and others).
Yes, that is interesting. I have never seen that stamp before. I wonder why it is described as "heavy duty" when it was the only one available...or was it?
Eric
Having different ID/part numbers for the different styles makes sense: 6 cyl vs 8 cyl, closed emissions vs open emissions, 2WD vs 4WD (although why they should be different is not at all apparent).
All 3 of mine are identical; 2WD, 8 cyl, open emissions. Only on has the stamp legible enough to photograph.
Interesting if nothing else. In 1966 they changed the oil bath on the 4WD trucks. I believe it has to do with extra baffling to help keep the oil in place while on some more extreme angles that were being achieved in them at the time.
