Part: 4-Terminal Wiring Harness Electrical Connector for Honda CT90 / Trail 90, CB175, CB200, CB350, CB360, CB450, CB550, CB750
Why You Need This: The plastic components on your vintage Honda motorcycle are prone to dry rot, and the multi-pin plastic terminal connectors in your electrical system are no exception. Over time, these connectors can crumble, crack, lose locking clips, or become packed with corrosion, making proper electrical connections unreliable. We once chased an electrical gremlin for weeks in a CB360 due to a corroded connector!
Honda CT90 / Trail 90, CB175, CB200, CB350, CB360, CB450, CB550, and CB750 models all used similar wiring harness components, making this replacement a perfect fit for your vintage bike.
The 4-terminal connectors were commonly used for the key switch connection, regulator/rectifier connector, and the stator coil connection in CB/CL360 Scramblers. Earlier models like the CB450 and CB175 used a round brown plastic connector with small pins (see our #3003 key switch as a reference). By the mid-1970s, Honda phased out the round connector in favor of this square spade terminal connector, making it a suitable upgrade for restoring your original wiring harness.
Our high-quality wiring harness connectors and brass spade terminals are made in Japan and will help restore your wiring harness to like-new condition. Sold individually as a package including the connector with terminals. We also include an extra male and female terminal because we know mistakes happen during installation. As always, Common Motor has your back.
This pack includes:
- Male plastic 4-terminal housing x 1
- Female plastic 4-terminal housing x 1
- Brass male spade terminals x 5
- Brass female spade terminals x 5
For proper installation, use our electrical terminal crimping tool for a clean and secure installation.
We also carry other vintage Honda wiring connectors:
Installation Tip:Buy the electrical terminal crimp tool—yes, you will need it! Proper installation requires three steps:
- Inner crimp: Secures the wire.
- Outer crimp: Clamps onto the wire insulation.
- Final squeeze: Give the inner crimp an extra squeeze with the crimp tool for added security.
For the best results, we recommend soldering all connections to ensure a permanent and reliable connection. The recommended wire size for these terminals is 16 gauge.
Once the terminals are installed, insert them into the plastic housing. Each terminal has a small locking barb that snaps into place inside the housing. Male terminals go into the female plastic housing, and vice versa for female terminals in the male housing. Once installed, they are very difficult to remove, so double-check before inserting them!
