Generic Headlight Floor Dimmer Switch for GM Vehicles — 3‑Pin with 2 ft 14 AWG Pigtail, Direct‑Fit OEM Replacement

Replace a worn floor‑mounted headlight dimmer with a direct‑fit OEM‑style 3‑pin switch and pre‑wired harness for GM vehicles.

If your classic Chevrolet, GMC, Buick, Oldsmobile or Pontiac has a brittle connector or a failing floor dimmer, this kit gives you a straightforward repair that matches original fit and function. The package includes a new floor‑mounted dimmer switch plus a 3‑pin plug with approximately 2 feet of 14 AWG automotive wire, making it suitable for restorations, hot rods, and routine maintenance on cars and trucks that used this style of switch from the 1950s through the 1980s and some later models.

Will this replace my factory floor dimmer switch?

Yes — the switch and connector are designed as a direct OE‑style replacement for GM floor‑mounted 3‑pin dimmer switches. The terminal configuration and mounting are compatible with the original equipment used across many GM makes and model years.

• Direct‑fit form factor for standard 3‑pin GM floor dimmer locations.
• Durable terminals for secure electrical contact and reduced resistance.
• Plug‑in connector recreates the original wiring harness interface.

How easy is it to install the switch and harness?

Installation is straightforward for anyone comfortable with basic automotive wiring and under‑dash work. The pre‑wired pigtail reduces splice work and reproduces factory connections, minimizing installation time and improving reliability compared with repairing old, brittle connectors.

• Comes with pre‑wired 2 ft of 14 gauge SXL automotive wire for robust connections.

Which vehicles and projects is this kit suited for?
