Questions: I am looking for the cable from the starter switch on a 1946 CJ2A, to the ignition switch, no solenoid setup. I found all the battery cables, but not this particular cable. Can you verify if this wiring kit contains this particular wire, and if so what gauge is it as I assume it is not 1 gauge like the battery cables. Very Respectfully,
Question By: DiggityKid on Aug 29 2019 1:29 PM
Yes, the harness will include the wire from the ignition switch to the foot mounted starter switch.

Questions: I have a 1947 CJ2A with F134 engine will this wiring harness work with this? Thank you
Question By: Kyle Brumfield on Apr 29 2019 10:51 PM
Yes, this would, you may have to change out a few end connections but even on that it would be minor.

Questions: I have a 1949 CJ3A with the F-134 engine in it. I have switched to a 12 volt system with an alternator. Will the CJ3A harness work with the F-134 engine or will it need to be customized?
Question By: Casey on Feb 3 2019 2:48 AM
They would be the same for the most part. You would just have to wire in your alternator per that unit.

Questions: I understand that this is made like factory, cloth coating, but under the cloth coating are these plastic covered wires? I want the classic look, but also really want the protection and durability of the plastic.
Question By: David on Sep 26 2018 3:11 PM
I cut open one of tthe cloth wires and it does have coating around the inner core to insulate from cloth itself.

Questions: except for turning signal wiring are there any major differences between Willys MB and CJ2A wiring harnesses? I've installed turning signals on my MB and I guess it'll be better if I use the harness where they're already included by you.
Question By: Archil Chrelashvili on Aug 26 2018 3:12 PM
There are differences in wire lengths and end connections. They are different harnesses.
Answer By: Willys Jeep Parts Tech on Aug 27 2018 5:54 AM
Questions: I had ordered and already received this harness. I have changed my mind and now do not want to go with the turn signal feature. How big of a deal is it to alter this harness so that it will work without the turn signal feature. Is it just a matter of not connecting a couple wires?
Question By: William Darrow on Aug 1 2018 3:04 PM
You can just tape off the wiring for it and not use. It wont effect anything. Its wound into the main loom.
Answer By: Willys Jeep Parts Tech on Aug 1 2018 12:14 PM
Questions: Do you only offer in the cloth sheathing, or can I get a harness made with the more modern (plastic?) sheathing? Any advantage to one over the other if being "period correct" is not important to me?
Question By: Tom on May 29 2017 2:46 PM
In these Willys years they would be cloth covered only. We make them to factory spec.
Answer By: Willys Jeep Parts Tech on May 30 2017 5:32 AM
This are modern wires, plastic coated, but with the factory cloth sheathing over to make it look factory. Best of both worlds.

Question By: Mark on Mar 1 2017 10:17 PM

Questions: Will this come with the hardware included in part number 947348? I get that this comes with the wiring for the turn signals, but I just don't see the turn signal hardware in the pictures.
Question By: Anonymous on Feb 24 2015 12:00 AM

Questions: Just placed the wiring harness above in my CJ2A (48). Cannot figure out why my my high beam indicator will not work on the dash. Unable to get power to the socket. I attached it to the high beam switch terminal on the floor along with the high beam cable. Also, there are no rear running lights. The rear lights work for braking and turn signals. Any ideas?

Question By: dave on Dec 11 2012 12:00 AM
