Wiring; Wiring for cj3b

Hi, this is my first post here. I'm a new proud owner of a '54 cj3b at least that is what it is titled as.
Well my question here is what is the essential components needed to wire up the ignition system, lights, and maybe a radio?

Right know the girl has the f-head with an alternator installed and basic ignition wiring just to make it run. And that is all the wiring it has. Waiting on so literature to come in the mail. So I thought in the mean time I would ask you guys.

All help is appreciated
Thanks

Mike,
Welcome and congratulations!

The first thing I'd suggest is to verify either 12V or 6V. This is important if you're considering adding things, i.e. radio. You mentioned you have an alternator so this implies someone has already converted it - even though its possible to have a 6V alternator.

You can begin by looking at the Sticky at the top of the Posts for Searching. Cut and Paste the bold text in your Google search, just like it says and then add words like wiring or rewiring to read what others have posted.

You can be as elaborate as building a board with nails to run and measure wire for each component or you can run each individual wire from where it starts (i.e. a guage or switch) to where it terminates and then bundle all the wires together when done.

Testing each circuit after connecting will help with troubleshooting as you go vs. trying to do the same after all the wires are taped together.

You'll also read about some color coding (either based on original or your personal custom colors) each wire or just buying a bulk spool and going at it.

If you're wanting to spend more $ you can order a pre-made wiring harness or have one built for you to include your specifics.

I would also recommend going to the Tech link on the 3B Page and read those electrical articles as well (includes wiring diagram).

When you are able, share a photo of your jeep!

First off, welcome to a wonderful and useful website where you'll find a ton of knowledge and expertise from some very helpful and friendly fellows.

What you need to do is look at a wiring schematic for your 3B. Go back to the HOME page and click on the SEARCH heading; once there, simply type in "3B wiring" and a page will pop up displaying the complete layout.

All you need to power a radio is a lead from either the accessory side of your ignition switch (if you have a key starter switch and not the floor button switch), or directly from the positive side of the battery. Radios mfg'd. today don't take a large power lerad, but I'd still recommend a min. 14 ga. lead, and also an in-line 3 amp fuse & holder.

Mike,
Congradulations on your recent jeep purchase and...
Welcome to the CJ-3B Bulletin Board !

The basic ignition system consists of both primary and secondary circuitry.
The lighting harness is a seperate system from that of the ignition system.
The radio is wired in as an accessory from the key switch.
Please indicate if your so called 1954 3B has a single cluster gauge or a 5 gauge dash panel.

When you get time pleae fill in your SIGNATURE with know data concerning your Jeep.

Shopman...Welcome, there is a wealth of info here for you to do whatever you need to do on your jeep. How far did you tear things apart? I did a wiring harness from Carl Walck, very happy with it.

Mike,
That's exactly how I did it at first. Lasted a long time like that. Easy to do.

BTW, where are you located?

Mike,
The link below provides instructions for construction of the post 1956 CJ-3B wire harness assemblies.
Post 1956 implies CJ-3B with cluster gauge instrumentation.
The FUEL WIRE, the HEADLAMP HARNESS, and the TAILLAMP HARNESS are identicle to the early CJ-3B;
excepting the wire insulation and the color code.

I wired up my jeep using bulk wire on spools and ran each wire one at a time. Had an absolute blast doing it. If you're going to run your own harness, I recommend a nice terminal crimper like THIS ONE. It will crimp the terminal perfectly every time. I am not a fan of those cheap ones that come with the terminal kits.
