🔌 CB400F / CB400 Super Sport Wiring Harness – 75-77 Four – Main Loom – OEM 32100-377-030

Bringing a ‘75–‘77 CB400F or CB400 Super Sport back to life?

You need this.

It’s the main wiring loom, brand new, plug-and-play as far as vintage Honda goes.

Matches OEM part numbers 32100-377-030 and 32100-377-020.

Made to route just like the factory setup.

No chopping, no guesswork.

It’s unbranded but don’t let that fool you—the pinouts are correct, the length is right, and it connects your ignition, lights, everything.

If your old harness is cracked, cut, or crispy, just yank it out and slide this in.

Saves hours of tracing wires.

Perfect for restoration or a ratty cafe build.

Classic four-cylinder juice, delivered clean.
