where can I find a copy of instructions for wiring up my cj2a, from foot switch to turn key.

Willys Jeep Parts Tech:

Will the detailed instructions show were or how the wires would be ran? Like were each wire would ran throw the fire wall and on the body. My original wiring is in pretty bad shape and is hard to till witch wire is coming or going.

Willys Jeep Parts Tech:
It shows where each end terminal goes. We can help with any questions you might have too.

If i buy item number HARNESS-02 in order to rewire my '47 CJ2A, will that still hold up okay if i have converted the vehicle to 12Volt?

Willys Jeep Parts Tech:
Yes, that is correct.

Does this harness have accommodations for a passenger side tail light? Does original CJ2A have one or two tail lights?

Willys Jeep Parts Tech:
Yes it does.

Is there a fuse box included? If not, got link? Thanks.

Willys Jeep Parts Tech:
They never originally used a fuse box.

Yes sir, my father and I recently acquired a 47 Willy’s Jeep, he wants to convert from the old 6 volt wiring to a new 12 volt system. Is that possible with your wiring harness?

Willys Jeep Parts Tech:
Yes, this harness works for both 6 and 12 volt.

I need to know how much does the package weights. Thank you. Regards, Rodolfo

Willys Jeep Parts Tech:
These are approx 7 pounds shipped.

Does this complete wiring harness come with all needed cables such as battery cables, spark plug cables, engine ground cable, etc.

Willys Jeep Parts Tech:
No, I'm sorry. Those items are all separate. The harness is sold with just the wiring. Please give me a call toll free and I can put together a quote for the rest of the items. 888.648.4923. Thanks

I installed one of these harnesses with an alternator not a generator. When I finished, my cj2a ran perfectly, the ammeter worked, but my head lights and tail lights didn't work. I haven't connected the brake switch yet. Any common problems to check?

Willys Jeep Parts Tech:
I would check your headlight control switch for sure. We have a diagram on available if you need it.

Will this kit come with detailed instructions?

Willys Jeep Parts Tech:
Yes, it will have wire for wire install instructions.

I have seen harnesses available from other companies where they ask if the horn is on the firewall or fender. My horn is on the left fender w/o turn signals. Is this the correct harness?

Willys Tech:
We custom make each harness and have several questions we have to ask you about your vehicle. Yes that is one of the questions but for it to be correct to your vehicle there are a few others as well. After you place your order we both call and email you to get some general questions answered.

good afternoon, i have a 52 M-38 converted to 12 volt. will this work with this jeep?

Willys Tech:
Yes, these are custom made so as long as you list you have a 12volt M38 we can get it done.

What gauges of wire does this come with and how many feet of each gauge?

Willys Tech:
It is the proper gauge material and lenght for each section of the harness and all preterminated and color coded with instructions.

I have a 12 volt system and purchased one of your alternators. Will this harness accomodate the alternator?

Willys Tech:
Yes it will work with it. The alternators come with wiring instructions.

Will this work on my 1946 cj2a that has been converted to 12volt?

Willys Tech:
Yes. Please call us toll free. We are more than happy to help out.

does a wiring diagram come with the wiring harness

Willys Tech:
Yes that is correct.
