GM 9L7 Upfitter Package + Custom Harness
The long-overdue and highly anticipated kit is finally here — and it’s for the 1500 Light Duty trucks that everyone said couldn’t be done. But we did it.
Just pick up a refreshed interior Silverado or Sierra and want factory-style auxiliary switches to hook up extra lighting or other equipment? This 9L7 Upfitter Auxiliary Switch Bundle is the solution you've been waiting for. It includes all Genuine GM parts, plus a custom-designed plug-and-play harness that makes installation easy and clean — no cutting, no splicing, no risky workarounds.
Just follow the included step-by-step instructions. No programming is required, and when you're done, you'll have fully functional switch outputs ready to power your lighting, gear, or other accessories.
This kit is specifically designed for the 2022–2025 1500 Light Duty trucks with the refreshed interior — the trucks GM never offered a complete upfitter solution for. Until now.

📌 This kit is made specifically for the 1500 Light Duty trucks with the refreshed interior — a configuration previously thought to be unsupported by GM. We built it, tested it, and made sure it works exactly as it should.
Why Choose 404 Parts?
This upfitter kit has been in high demand, and GM’s spotty availability hasn't made it easy to find complete, compatible setups. We've sourced every part and even built our own harness to give you a full, ready-to-install kit with no backorders or guesswork.
Everything is in stock, ships fast, and installs right — even on the trucks GM didn’t support.
