Here is a completely manually redrawn vector graphic Laminated Full Color rendering of the Honda Wiring Schematic for the Honda CT90 / Trail 90 Motorcycle.
This is a quality drawing.  All colored wires have black outline for greater definition, making it easy to trace those wires!
Over 25 hours in recreating this diagram in high quality color.
If you are looking to make repairs, understand the circuits, or rebuild a wiring harness from scratch, this diagram should prove invaluable. 
No more fuzzy, difficult to trace black and white scans.

Covers K2 through early K6 (1970 through early 1975). 
Buyer must verify on the later models.  I'm happy to answer questions.


Laminated for long life and to help protect from garage / shop greasy finger handling. 
The 11 x 17 size makes it much easier to see / trace connections. 
This is a robust print!

These also make great dining place-mats for your man-cave.  Suitable for framing.  (Only CT90 lovers will understand...)

Please review photos and ask any questions you might have prior to purchase. 
Guaranteed accurate to the actual Honda manual. 


Note:  Some variation for a few odd wire colors was done by Honda for the date range of 1970 through early 1975, but the wiring is correct.
The colors on some wires may be different than depicted depending on the year of your bike.  This one is accurate for 1974 exactly.
As an example, the two wires for the ignition, one may be a different color than depicted on this drawing depending on the year.  But the schematic wire diagram is not affected.  The actual wiring is still accurate. 

Thanks for having a look!
