Wicked Wrench Pro-Series Gen V Jeep JK/JKU Integration Harness

The ultimate standalone plug-and-play wiring solution to bring Gen V LT automatic power to your 2012+ Wrangler.

Swapping a modern GM Gen V direct-injection V8 into a 2012–2018 Jeep Wrangler JK/JKU used to mean dealing with incomplete wiring, unreturned tech calls, or sacrificing your core dashboard functionality. The Wicked Wrench Pro-Series Integration Harness solves the heavy lifting. Fully engineered, built, and rigorously tested in the USA, this premium harness delivers a clean factory-level bridge between your new automatic GM powertrain and your Jeep’s factory network.

🧩 Factory Integration Breakdown

We believe in 100% transparency so you can plan your build accurately. Our integrated module retains your core factory comfort and diagnostic features while dropping the highway fluff you don’t need:

• Full Factory Gauge Support: Your factory speedometer, tachometer, fuel, oil pressure, and water temperature gauges work perfectly right on your dash cluster.
• Total Comfort Control: Full factory air conditioning integration utilizing modern safety cutoffs based on automatic GM RPM and pressure metrics.
• Off-Road Ready: Keeps your factory ABS, cabin accessories, power windows, and electronics fully powered and operational.
• What is Deleted: To streamline the swap electronics, you will lose traction control (perfect for the trail, and street anyway!), factory cruise control, and steering wheel-mounted menu/audio controls.

🔧 Automatic Transmission Setup Options

Select your transmission options from the dropdown menu above before adding it to your cart. Pricing starts at $2,400.00 and varies depending on your chosen drivetrain setup. All configurations are pinned and mapped for factory-level electronic shifting and safety interlocks:

• GM 6L80 6-Speed Automatic Setup
• GM 8L90 8-Speed Automatic Setup
• GM 10L80 10-Speed Automatic Setup

📝 Product Details & Compatibility
