9L7 Upfitter Package OEM Switch Kit for Custom Install

The long-awaited upfitter kit for the 2022.5–2025 GMC Sierra 1500 AT4 and Denali is finally available.

If you’ve been looking to add factory-style auxiliary switches to power lights, tools, or other gear, this is the real deal — genuine GM components combined with our 404 Parts 1500 wiring harness, designed to deliver the OE look and function you’re after.

The wiring side of this kit is fully plug and play with no programming required. Once installed, you’ll have five clean 12-volt outputs ready to go.

A Quick Note on Installation

Because GM does not currently offer a factory dash panel for switch integration on the 1500 series, this kit requires you to choose your own mounting location. Common placements include in front of the instrument panel cluster (IPC) or inside the center console.

Our instructions will walk you through dash disassembly, and we’ve included real customer-submitted photos to help visualize different mounting options. Final placement and any trimming are up to you. If you’re not comfortable with the custom mounting portion, we recommend having a professional installer assist.

👉 To help with flexibility, this kit includes a custom version of the OEM switch bank that features a 4-screw mount instead of GM’s standard clip-in setup — ideal for secure custom placement.
👉 If you're mounting farther away, we also offer extension harnesses to make relocation cleaner and easier. Buy now to save time — see the “Frequently Bought Together” section above for a one-click add-on.
