I recently purchased a wiring harness for my 65 CJ5 project from Walck's and it worked wonderfully. I have a 58 CJ5 that I will be needing a harness for in the next 6 months or so and am wondering... since you recently acquired Walck's business due to his retiring if the harness I would eventually purchase through you would be of the same quality and design?

Recently purchased the wiring harness for a '64 CJ5 and in the process of installing it and have a question regarding the heater. I don't notice any reference to any wiring for it. There are three (3) wires coming from the heater, red, yellow and black. I'm assuming the black is a ground and the red and yellow go to the tabs on the heater control. Just wondering where the power comes from. Also, noted with the harness there are two yellow and two blue wires in the kit with one end without a connection and the other ends have a male bullet connector attached. What are these four wire for? There is no mention in the included wiring diagram that I can see.
Willys Jeep Parts Tech:
Most didnt have a heater from the factory. You would have to wire in your heater thru the switch for it. You can email us some photos and we can try to help.

I'm restoring a 1958 cj5..does this harness include the temperature and oil pressure sending units (switches) that work with the instrument panel and go into the block? Since this model has no actual temperature and oil pressure gauges, I figure the sending units must be some type of pressure or max temp switch that would illuminate the corresponding lights in the instrument cluster.
Willys Jeep Parts Tech:
The actual switches/senders are not part of the harness. But it has all the wiring going up to them.

Customer # 265293, with over $2,300 in parts, I just need a Wiring Diagram. Can you send me a WIRING DIAGRAM for a 1955 Jeep CJ5. This Jeep came off a pecan orchard. It has not been used in years. Top of Transmission Froze from rust, Ok now and change oil twice. Engine and transmission, rear-end and transfer cases are fine. I have had it running and drove a couple miles. Now, I want to finalize the wiring. Many wires were cut, others spliced with non-matching colors. I've pulled all the dry-cracked conduit off. I need assistance on the brake/turn signal wiring, headlights and park/turn signal lights in front, horn is there but need to wire to relay and horn button. There is also a rheostat in front of radiator, no wires to it. A complete DIAGRAM will finalize this for the road. Thank you, Jim Bertzyk

Hi. Can you wire the harness for working with an alternator and not a generator with a voltage regulator?
Willys Jeep Parts Tech:

I have a 1964 CJ that I purchased about a year ago. It has a ford 289 with an electric distributor under the hood, would this harness work for this set up?
Willys Jeep Parts Tech:
Typically the motor doesn't change too much on the wiring as long as they have not moved things on the to or from the fenders or firewall. You would have to change some connections on your end for the starter or generator, ect.

When you says "includes turn signals" does it include the switch that mounts on steering column, or does it just it has the wires to go to it? Is there a particular fuse block you recommend? Elsewhere in Q & A it's stated that this will work with vehicle that have been converted to alternator, but "as is" or with mods? -- and do the wiring instructions provide that info? Thanks
Willys Jeep Parts Tech:
It includes the wiring at your turn signals. The turn signal switch is a separate item.

Recently purchased wiring harmes, w/turn signals. Are there diagrams for wirimg this harness without turn signals. Maybe color coded to match wires?
Willys Tech:
All you have to do is tape off the wires that go to the turn signals. That's pretty much it if you are not wanting to run the pre-loomed in wires for the turn signals.

I'm a new owner of a 1965 CJ-5. My new toy has wiring issues and I considering purchasing a complete new harness for it. Do you recommend using a fuse block along with the new harness?
