1979 Honda CB400TII Hawk II · Fuse Box Buying guide

Check the fuse box and the connector together

This route offers a complete replacement fuse box with fuses included. Inspect the electrical and mounting connections before ordering, and distinguish damaged hardware from a circuit fault that keeps blowing a fuse.

Buy the assembly when the hardware needs it

Look closely at the fuse clips, plastic housing and mounting ears. If those parts are damaged, replacing only a fuse leaves the hardware problem in place. Compare the plug and lead arrangement before ordering the complete assembly, particularly on a bike with previous electrical repairs.

Keep the original circuit protection requirements

Included fuses do not change the motorcycle’s circuit requirements. Check the correct Honda wiring information and the fuse ratings for each position before use. If a fuse repeatedly opens, diagnose the circuit; fitting a higher-rated fuse is not a remedy for a recurring fault.

Common buying questions

Are fuses included with the replacement box?

Yes, the complete fuse-box assembly includes fuses. Check each fitted rating against the correct Honda circuit information before use, especially if the existing fuse box or wiring has previously been altered.

Will it connect to a modified wiring harness?

Compare the connector shape and terminal arrangement first. The assembly follows reference 38200-413-003 for the 1979 CB400TII application; a modified harness may require its connections to be identified before compatibility can be confirmed.

Will a new box fix a fuse that keeps blowing?

Only if the failed box is the cause. A recurring blown fuse calls for circuit diagnosis, including wiring and connected components. Replace damaged fuse hardware as needed without raising the specified fuse rating to hide the fault.
