1977 Honda CB750F · Electrical Buying guide

Match the wiring and equipment actually fitted

Start with the exact main-harness and control references, then identify the ignition equipment fitted to the motorcycle. A product’s model application does not by itself establish the routing, mounting or connections needed by changed components.

Identify the loom and separate electrical components

Horn subharness 73-0112 references 38105-410-671 and lists the 1977–78 CB750F. Flasher 10-1170 references 38310-415-671 and lists the 1977 F specifically. Fuse box 10-6000 references 32110-341-702 and includes the 1977–78 F among its applications. Check each component against the fitted equipment rather than treating the main loom’s application as proof of every connection.

Choose coils for the ignition being retained

Stock-style coil 17-6823 is listed for contact-point ignition and has 100 mm mounting centres. Dyna S 07-9988 is an electronic ignition module supplied without coils or spark-plug wires; its listing specifies suitable stock coils or aftermarket coils with at least 3 ohms of primary resistance. Confirm the fitted ignition and the coil manufacturer’s compatibility requirements before ordering.

Electrical selection questions

What must a replacement handlebar accommodate for the selected left switch?

Switch 12-0310 references 35200-410-671 and is listed for the 1977–78 CB750F. Its wiring is designed to run inside the handlebar, and the supplier requires suitable internal-routing holes. Confirm that the handlebar fitted supports that arrangement before choosing the switch.

Do the regulator’s stock-type plugs mean its mounting will also match?

No. The 24-2109 listing specifies a 68 × 94 × 26 mm body and mounting holes 80 mm centre-to-centre, and warns that custom mounting may be required. Compare that envelope and hole spacing with the available mounting location as well as checking the connections.
