1971 Honda CB750K · Wiring harnesses Buying guide

Replace the damaged wiring section with the matching listing

The main loom and two smaller wiring assemblies serve different parts of the motorcycle. Use the location of the damage and the connector description to select the appropriate item, then check its stated application.

Confirm the application before buying a complete loom

The main harness description warns that different CB750 years and types use different references. A 1971 collection narrows the search, but modified controls or connectors still warrant comparison. Check the fitted equipment and review the complete product information before committing to the main harness.

Keep small wiring repairs focused

The alternator stator harness and oil pressure wire are separate assemblies, not complete main looms. Compare which wires and connectors are damaged before choosing between them. The oil pressure wire includes a rubber cover, while the stator listing identifies its seven-wire connector.

Questions about wiring harnesses

Is the main harness universal across CB750 models?

No. The product specifically limits this loom to the listed 1969–71 CB750K and notes that other years and types differ. Compare the application and installed equipment; do not choose a complete harness solely because the bike is a CB750.

How is the alternator harness connector described?

Its description identifies a seven-wire plug matching the stated original application. Compare your existing stator connection and product information before purchase, especially if the motorcycle has replacement charging equipment or altered wiring.

Does the oil pressure wire assembly include the pressure switch?

The listing supplies the wire and rubber cover. It does not list a new switch among its contents. If diagnosis identifies the switch rather than the connection as faulty, compare the separate pressure switch listing in the switches category.
