Jeep JK Wrangler Tuner Shootout
|
The JET Stage 1 module and Unichip Plug-n-Play Kit install underhood. This requires disconnecting the battery and removing either one (for the JET unit) or two (for the Unichip kit) of the factory wiring harness connections from the Powertrain Control Module (PCM). The PCM on a JK is located on the driver-side inner fenderwell, just behind the radiator and windshield washer reservoir. View Related Article
