    Simplified 78 Honda CB400T Wiring Diagram

    Hi there,

    After struggling to understand the stock wiring diagram to reduce the wiring mess for my CB400T Cafe Racer project I came up with my own diagram:

    Simplified 78 Honda CB400T Wiring Diagram-cb400.png

    Blue blocks are switches, yellow are lights and grey are devices. They are disposed similar to the real places on my bike.

    I hope you find use for it. If not for real use, at least as an overview.

    Cheers!

    Took a bit to understand your circuits but it looks good. The turn signal relay is a 3 prong instead of the normal 2 prong.

    Glad you got it. In this diagram I chose to ignore the panel lights and replaced all the wiring between CDI and Pulse Generator for a simpler thicker line.

    It was intended for use on a custom build where aftermarket parts such as speedometers and lights are often used as replacement.

    The 3 prong relay is better as it maintains a steadier pace regardless of the load in mine opinion. It is also the choice when using LED.

    If you have any other questions or advice please share!
