1978 Honda CB400TI Hawk I · Ignition Parts Buying guide

Match key-switch and plug-cap connections

The rectangular-plug key switch and XD05F cap provide two distinct repair choices. Select by the component needing replacement, then compare the relevant electrical connections rather than relying on the shared CB400 name.

A matching connector comes first

The key-switch application is conditional on a rectangular connector block. Compare its six terminal positions with the bike side of the connection, and check the mounting before ordering. A switch that looks right at the key barrel may still connect differently underneath.

Keep the plug and lead in view

Inspect the cap together with the spark plug and ignition lead. The featured cap is XD05F type; use that identification when comparing replacements. Do not choose a cap only by its outside shape, and do not infer a complete set from a single-cap product image.

Buying questions

Will the switch work with a modified wiring harness?

Only choose it after confirming the harness connection and terminal arrangement. This switch is specifically the rectangular-block version with six flat male terminals; a changed loom may need a different connection.

What should I check before buying the plug cap?

Check the cap type, spark-plug terminal and ignition-lead connection. Compare the XD05F specification with the cap being replaced, rather than assuming any angled cap will suit the fitted plug and lead.

Will the new ignition key also operate my helmet lock?

Do not assume separate replacement locks will share a key. The ignition switch and helmet-holder lock are separate products; arrange any matched-key requirement before ordering rather than planning around the original key.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
