1979 Honda CB400TII Hawk II · Ignition Switch & Caps Buying guide
A replacement key switch must agree with the harness connection. A plug cap must suit the lead, plug terminal and available clearance. Keep both checks specific to the parts currently fitted.

An old motorcycle may have a replacement ignition switch, repaired connector or spliced harness. Compare the plug shape, flat terminals and mounting lugs before ordering. If the wire arrangement has changed, have it identified against the correct wiring diagram rather than adapting a new switch by color alone.
Look at the terminal on the installed spark plug and inspect the end of the high-tension lead. The XD05F designation identifies this cap choice, but a changed plug or lead still needs a connection check. Examine both sides of the twin rather than assuming previous replacements match.
First identify the replacement connector and its wiring. This switch is intended for a rectangular block with six flat male terminals. A different plug needs a verified wiring solution before the switch can be selected confidently.
Matching the replacement ignition assembly to your existing seat or steering locks is not established. If keeping one key for all locks matters, confirm the keying before ordering.
Compare the spark-plug terminal, lead connection and angled entry with your existing cap. Pay particular attention to changed spark plugs or non-original leads, and check that the cap can seat fully without stressing the lead.
