1972 Honda CB175K6 Ignition Parts

Identify which ignition component needs replacement before building the order. The round-plug switch has a specific connector, while contact points depend on the ignition maker. On a 1972 CB175K6 restoration, checking the fitted parts is especially important when previous electrical work is unknown.

1972 Honda CB175K6 · Ignition Buying guide

Identify the switch plug and ignition maker

The featured switch uses a round six-hole, four-wire connector. The linked coil and Nippondenso points address different ignition repairs; identify the fitted ignition equipment before choosing those replacement parts.

Confirm the switch connection before the order

This ignition switch is intended for a round harness connector and carries references 35100-303-007, 35100-292-003 and 35100-292-013. Compare the fitted plug and circuit information. Those references identify the offered product; they do not establish the wiring of a substituted harness.

Keep ignition-maker restrictions in the decision

The linked contact points supply one piece for Nippondenso ignitions only; they do not fit Hitachi or Kokusan systems. The separate linked coil replaces 30400-306-673 and 30400-306-672. Check its mounting and connections against the existing coil; no mounting-center dimension is specified.

Buying questions

Can the Denso points replace any points in this range?

Choose these only for Nippondenso ignition equipment. They do not fit Hitachi or Kokusan systems. One piece is supplied; identify the installed points system before ordering.

Is this ignition switch a six-wire unit?

It is described as a four-wire switch with a six-hole round connector. Compare the harness plug and the required circuit connections so the number of holes is not mistaken for the number of wires.

How should I check a replacement coil?

The linked coil replaces 30400-306-673 and 30400-306-672 and covers CB175K models from 1970–73. Compare the actual mounting and connections; obtain a mounting-center measurement if a changed installation requires one.
