I need to make a new wiring harness for my Model N, does anyone out there know the correct wire colors Henry might have used? This would be the battery box wires and the timer wires. Thanks for any help, I've already posted on the Early Ford Registry, but no reply's. Thanks for any help!Bob
I used a 26-27 T wiring harness from the box to timer. I don't know what the original looked like, but this is a simple way to keep everything in place. It's difficult to see the wire (back of the camshaft timer to bottom of the coil box), and the harness will soon be grease and grime covered.
Thanks for the info, mine seems to be original, but hanging on by a thread! Also to greasy to identify any colors. I'm just going to move on as you suggest.
There is a wiring diagram with colors listed in the electrical system section of Pate's Early Ford Encyclopedia. Can't reproduce it here because of copyright, sorry.
Copyright should be expired by now. And since you are not showing it for monetary gain, I do not think there is any reason not to post it.
I'd like to know the proper routing. I was working on one and it was close enough to the exhaust manifold that it was getting scorched. That's a tough thing to avoid given the placement of the timer. Is there supposed to be any kind of shield?
Hey Mark, I do have Pate's book and see the wiring diagram in section 10, page 7, but don't see any colors. I also looked on the CD, but don't see anything, am I missing it? Thanks Bob
Two thoughts come to mind. First recommend you contact Trent Boggess. He has a very original 1908 Roadster. And he loves details about the early cars.
Second, the Henry Ford Museum has an excellent original 1907ish Model N Ford on display. It might also have the original wiring.
Finally, if you do find some additional clues please let folks know.
Not requested -- but would be part of the ignition on the N,R, S, & SR cars -- reproduction old style dry cell labels etc. See: http://www.radiolaguy.com/Batteries/Vintage_Batteries.htm

Oops, sorry, my bad Bob, I was looking at the 1903-1905 diagram on the previous page, it has the wire colors called out in text.
Here is a link to some early Ford manuals:
Rob Heyen has a Model N, perhaps he can chime in with the wire colors on his car.
Also, here is a link to Carlton Pate's early Ford web page, perhaps contact Carlton direct?

Above I mentioned we used a 26/27 harness, as it was similar in length to what we needed. I'll go back to my old photos and see if we took any of the original loom, although I think they were very discolored.
These photos from an English sales brochure don't show much, however may be useful generally. The link to the brochure is included. Courtesy of the Detroit Public Library:
For my N, I just used appropriate looking clothe covered wire and bundled them with the aluminum wire ties from Restoration Supply Co. It looks period correct. http://restorationstuff.com/catalog.html
