I created a post with a list of wiring schematics, but it was deleted somehow. This page provides a temporarily replacement.  I’m sure I had links to where I found these, but I will have to relocate them.

    Hi Ken,

    I tried to email you the following, but the email bounced back:

    Hi Ken,

    I managed to track down a willys wagon wiring diagram (actually, the
    entire manual). This is a PDf posted at the old Willys Forum:

    Once you download the PDF you’ll have to scroll to the electrical
    section. Let me know if you have any trouble with it.

    If you get a chance, you might thank the folks over at the old willys forum for scanning
    and posting it. Here’s the thread:

    Have a Happy New Year!

    I am looking for any Diagrams, description & operation on a 1949 willies jeepster flat 4 overdrive system. Just replaced a bad overdrive solenoid but something else is wrong in combination. Do you have those resources? Thanks for any help!

    Hi Mark,

    Here’s a list of schematics that includes a couple different Jeepster schematics (near the bottom of the page). However, neither the Jeepster nor the wagon schematics include the overdrive wiring.

    Could this switch need replacing?

    Here’s a break down of the Borg-Warner R-10:

    Here’s a general look at some problems with the R-10:

    Here’s one example of a borg Warner overdrive schematic:

    Does any of that help?

    Do you happen to have a wiring diagram for a DJ m35u? Mine has the floor lever to actuate the starter. I am desperately trying to find a wiring diagram but not having much luck.

    I’m not sure what a DJ m35u is? Could that be a misprint? Is it some kind of DJ-5?

    I know this is old and no one will probably see it but I have a dj-5 postal jeep that I cannot find the wiring diagram anywhere

    Hi James,

    What year is your DJ? I’ll see if I can locate something.

    Good day.
    I am in search of a 1956 willys cj5 wiring diagram and cannot seem to find one, if you would know where to get one it would be appreciated.

    I got a dj5 from 1975 I really need help, were rewiring this this I need a original wiring diagram I’m muttering through but I can get the stop and charging systems to work

    Hi Julian,

    You can buy one for the DJ-5F on eBay for $15:

    I used to be able to find manuals like this in libraries, so you can try checking with a local library to see if they have one.

    Finally, you can contact, explain what you are doing, and see if they can send you scan.

    Sorry I can’t be more helpful. Best of luck!

    I’m trying to restore a 1955 cj5 all the wiring has become rat food and is missing. I keep getting mixed information 6 volt not 6 volt. it is still running a generator not an alternator. no battery the rear brake built appears to be 12 volt. I want to restore to original. do you have the wiring diagram?

  15. David Eilers

    Hi Benjamin,

    I don’t have one offhand. I recommend asking the folks at the page. Someone there ought to have one.

    – Dave
