Jeep Wrangler JK Electric Add-OnsPosted in How To: Electrical on August 1, 2012 Comment (0)
The ’07-present JK Wranglers have a CAN-BUS electrical system. We’ll save you the trip to Google: it’s a fancy way of saying “teeny, tiny wires that are all but impossible to add aftermarket electrical gizmos to.” It lets auto makers pack a ton of electrical trinkets into a very small space without having to run enormous conduits of heavy-gauge wire throughout the vehicle. Models like Ford’s Raptor pickup have CAN-BUS systems that include factory in-dash switches and hook-ups for aftermarket electrical accessories such as off-road lights, satellite GPS systems, X-ray-vision specs, and stuff like that. Jeeps, not so much. You’re on your own—or at least, you’re knocking on Precision Designs door for one of the company’s sPOD systems.
The company has just upped the ante in accessory power distribution with the evolution of the Generation II sPOD system. That’s one whole generation more betterer. No more splicing into the cigarette lighter for power, drilling holes into your dash for switches or dealing with a spider web of multi-colored wires shooting out of your battery. That’s right—it bypasses the factory wiring altogether.
The sPOD consists of a factory-appearing aluminum switch panel populated with six switches, available in your choice of amber, blue, green or red actuators. The switch panel fills the void in the unused space on the upper windshield frame, between the sun visors. There’s no need to drill or cut a single hole with the sPOD, it’s a simple bolt-on procedure. The pre-wired two-piece wiring harness from the switch panel routes along the windshield frame, down the A-pillar, and through the firewall. Improvements to the Gen II sPOD include a single-snap plug end that connects to the power box with a Deutsch automotive connector. The plug end easily passes through the firewall and snaps into the source box, shortening installation time by 10 to 15 minutes. In addition to the items offered in the Gen I sPOD, the six-circuit power control module is the brain of the system and offers an integrated LVCO (low-voltage-cut-off) circuit that detects the battery voltage and will cut-off at 10.6VDC and cuts-back in at 12.4VDC. In laymen’s terms, this means there’s enough juice to start your vehicle in case you left an accessory on. The second update to the source box is the integrated external inline fuse, which again helps simplify installation and alleviates any loose wires to tie down.
