1946 Jeep CJ-2A Rewiring Made Easy

    Our ’46 CJ-2A gets a Walck’s electrical wiring harness and fuel tank

    It doesn’t get any better than bringing your project Jeep’s body home from the paint shop. This technically means you’re rounding third base on the restoration and heading for home plate. But before those seats go in and the fenders go back on, there are some important items to be installed first—the wiring harness and fuel delivery system, for instance.

    Keeping the gremlins away from any project sometimes means completely replacing these key drivability and reliability systems to get it done right the first time. Here’s where Walck’s 4 Wheel Drive scored big points with us. Walck’s is a one-stop shop for Jeep restorations, and among its many offerings is a high-quality 2A Wiring Harness made specifically for that Jeep’s lighting, horn, and accessory systems. A steel reproduction fuel tank for the 2A is also available through Walck’s.

    The Walck’s period-correct wiring harnesses are custom-made for each Willys Jeep application and come with all the correct-size eyelets, covers, and connectors ready to go for easy installation. Walck’s also has whatever else you might need to finish the electrical aspect of your project, such as voltage regulators, amp gauges, firewall grommets, and even 6V generators. We added an N.O.S. Sterling “Made in USA” 6V regulator Walck’s had in limited quantities to our shopping list, knowing it would add to the vintage appeal of the engine compartment. A new OE-style Olaco reproduction steel fuel tank, as well as the sending unit with brass float, fuel gauge, and steel lines were also ordered up to make sure we didn’t have any issues with rust or any other particles that can cause problems in your fuel lines or carburetor later.

    Taking your time and thoroughly reading the supplied installation instruction sheet supplied with the Walck’s wiring harness before diving in will certainly keep things going smoothly and help avoid any wire routing or costly hookup mistakes. Also, when moving to the fuel delivery system, make sure to pre-check the hard line male and female fitting going into the bottom of the fuel tank prior to installing it in the Jeep, as you will likely need to clean some of the paint out of the threads to get a leak-free seal. If you install the tank first and then try to check the line fitment from the bottom of the Jeep, it will be a lot harder than if you have it on a waist-high worktable directly in front of you to clean out the threads.

    The best part about this chapter of our ’46 Jeep CJ-2A build is that we didn’t have to be an electrical engineer to tackle the install. Walck’s 4 Wheel Drive made it easy. Check out the following photographs for the major steps, and some tips and tricks we learned along the way, as we installed the wiring harness and fuel system on our nearly finished project 2A.
