Questions: 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.
Question By: david cartledge on Jan 4 2022 3:01 AM
The actual switches/senders are not part of the harness. But it has all the wiring going up to them.

Questions: 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

Questions: Hi. Can you wire the harness for working with an alternator and not a generator with a voltage regulator?
Question By: Ole-Even Nebbenes on Mar 24 2021 6:02 PM
If you have an aftermarket alternator you would just have to wire it up accordingly. You may just have to swap out a few end connections.

Questions: 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?
Question By: nathan franklin on Sep 23 2019 4:25 PM
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.

Questions: 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
Question By: Jack Stanton on Jun 26 2016 4:05 PM
It includes the wiring at your turn signals. The turn signal switch is a separate item.
Answer By: Willys Jeep Parts Tech on Jun 27 2016 5:50 AM
Questions: Recently purchased wiring harmes, w/turn signals. Are there diagrams for wirimg this harness without turn signals. Maybe color coded to match wires?
Question By: C T Francis on Mar 18 2015 12:00 AM
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.

Questions: 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? If not, what provides the protection for a short or over loaded circuit? Can a fuse block be purchased thru you? How many circuits do I need to provide for?
Question By: Craig on Sep 20 2014 12:00 AM
The fuse blocks were never original but they are not a bad idea to wire in. They are a local Napa item.
