Posi-Lock Electrical Wire Connectors (10-Pack) for Vintage Honda Motorcycles
Posi-Lock connectors are high-quality, reusable electrical wire connectors that replace cheap automotive butt splice connectors on your vintage Honda motorcycle. Made in the USA, these connectors are vibration proof, require no special tools to install, and can be removed and reinstalled multiple times. We have been running Posi-Lock connectors on our shop bikes for thousands of miles with no issues.
Why You Need This
If you have ever pulled apart a vintage Honda wiring harness, you have probably found the previous owner's handiwork: cheap butt splice connectors from the auto parts store, crimped on with pliers (or worse), already corroded and wiggling loose. Traditional butt splices are held in place only by the pressure of the crimp. Over time, vibration works them loose and they fail, leaving you stranded.
While soldering and heat-shrinking remains the gold standard for permanent wiring repairs, it requires a soldering iron, flux, heat shrink tubing, and the skill to do it right. Posi-Lock connectors bridge that gap. They install in minutes using only your fingers, lock mechanically to the wire strands, and stay put through years of riding. We originally discovered Posi-Lock products when developing wiring solutions for our Shockwave electronic ignition kits, and have used them across every model we support ever since.
Available in three color-coded sizes to match different wire gauges, Posi-Locks are an essential addition to any roadside tool kit for your Honda CB350, CB360, CB450, CB550, CB750, or any other vintage Honda.

Important Notes
- Gauge selection: Most wires in a vintage Honda wiring harness are 16 gauge. The Blue Posi-Lock (14-16 AWG) is the rated size for standard Honda harness wires. However, for single-wire repairs the Red Posi-Lock (16-24 AWG) also works well on 16-gauge Honda wire.
- Select your size before ordering. Each 10-pack contains one size only — make sure to choose the correct gauge range for the wires you are working with.
- Not a substitute for full harness repair. If your wiring harness has extensive damage (melted insulation, corroded ground wires, multiple breaks), a full harness replacement or professional rewire is recommended. Posi-Locks are ideal for isolated repairs and modifications.
Installation
- Strip approximately 1/4" (6 mm) of insulation from each wire end.
- Unscrew both threaded caps from the Posi-Lock body.
- Slide a threaded cap over each wire end.
- Slightly fan out the exposed wire strands. Do not twist the strands before inserting them into the connector.
- Insert the wire and cap into the Posi-Lock body. Push the wire in while threading the cap onto the body until finger-tight.
- Repeat for the second wire on the opposite end.
- Give each wire a gentle tug to confirm it is locked in place. If it pulls out, strip slightly more insulation and try again.
To remove, simply unscrew the threaded caps and slide the wires out. The connector can be reused immediately.
Frequently Asked Questions
Which color Posi-Lock do I need for my Honda?
Most wires in a vintage Honda wiring harness are 16 gauge. The Blue Posi-Lock (14-16 AWG) is the rated match. The Red Posi-Lock (16-24 AWG) also works for single-wire 16-gauge repairs. The Yellow Posi-Lock (10-12 AWG) is for heavier gauge wiring not typically found in Honda harnesses but useful for battery cables or aftermarket accessories.
Are Posi-Locks waterproof?
Posi-Locks are not marketed as waterproof, but they do provide a tight mechanical seal that resists moisture and vibration. For connections exposed to direct water spray (such as near the front fender), wrapping the installed connector with electrical tape or heat shrink adds extra protection.
Can I reuse a Posi-Lock after removing it?
Yes. Posi-Locks are fully reusable. Unscrew the threaded caps, remove the wires, and the connector is ready to install again. This makes them ideal for diagnostic work where you may need to connect and disconnect wires multiple times.
How do Posi-Locks compare to soldering?
Soldering and heat shrink remains the most permanent repair method. Posi-Locks provide a semi-permanent, vibration-proof connection that is faster to install, requires no special tools beyond wire strippers, and can be undone without cutting wire. For roadside repairs, trail riding, or situations where you do not have a soldering iron available, Posi-Locks are the best alternative.
