American Autowire GM Steering Column Connector Kit 1969+ — 3-7/8" & 4-1/4" Housings with Complete Terminal Set

Complete wiring connector kit for 1969 and later GM steering columns — includes matched male and female connectors in 3-7/8" and 4-1/4" sizes plus all terminals needed for a clean, reliable column harness connection.

This American Autowire 500428 steering column connector kit is engineered to restore or update wiring connections on GM steering columns from 1969 onward. It supplies both connector halves for two common GM column plug sizes and a full set of terminals, helping you rebuild or repair the column harness without splicing or improvisation. The kit is designed for hobbyists and professional restorers who want factory-style fit and simple installation when servicing turn signals, horn, ignition switch connections and other column-mounted wiring.

What exactly comes in this steering column connector kit?

The kit includes matched male and female housings for the two most frequent GM column plug sizes, along with every terminal pin and socket required to populate them. That means you receive ready-to-crimp terminals and housings so you can recreate the original plug assemblies or replace damaged connectors.

• One male and one female 3-7/8" connector housing
• One male and one female 4-1/4" connector housing
• Complete assortment of crimp terminals for both connectors
• Parts packaged for easy identification during rebuild

How will this kit simplify my steering column repair?

Using matched housings and correct terminals eliminates guesswork and messy splices, producing a durable, serviceable connection that mirrors OEM assemblies. The included terminals let you crimp factory-style contacts to your existing wires, so replacements plug together cleanly and retain mechanical locking features.

• Restores plug-and-play connector functionality
• Prevents unreliable tape or butt-splice fixes
• Makes future disassembly and troubleshooting straightforward
• Reduces corrosion risk by enabling proper sealed contacts

Which GM models and years will this fit?

The components are specified for GM steering columns from 1969 and later that use the standard 3-7/8" and 4-1/4" column plug formats. If your column shows either of those plug sizes, this kit supplies the correct replacement housings and terminals for reassembly.

• Designed for 1969 and newer GM steering columns
• Works where 3-7/8" or 4-1/4" connector formats are present
• Ideal for classic GM cars and trucks with original-style columns

What tools and skills are required to use the kit?

Basic wiring tools and a modest level of electrical DIY skill are sufficient: you’ll need a proper crimp tool for the supplied terminals, wire strippers, and optionally dielectric grease for protection. Clear labeling and matched housings speed the process; if you’re unsure, a wiring diagram or photos taken before disassembly help place each wire correctly.

• Wire strippers, quality crimp tool, and small pick recommended
• Moderate soldering skills are optional but not required
• Follow wiring diagrams or reference photos for proper pin placement
• Dielectric grease can improve long-term contact reliability

Who this kit is for: The American Autowire 500428 steering column connector kit suits restoration technicians, DIY classic car owners, and repair shops aiming for a factory-like connector repair without sourcing individual pins or housings. It’s especially useful when original column plugs are brittle, corroded, or missing and you want a tidy, serviceable wiring solution that matches common GM column plug sizes.
