Customer Question

I need a wire Diagram for an 1999 Honda TRX 450 ES. The reverse light continuously stays on and the bike has no fire. I replaced the wire harness, right angle sensor, ES cluster, speed sensor and the reverse switch (at the handle bars). But still the same
problem. The ES is not working but you can shift the bike manually. No matter what gear you shift it to the reverse light stays on. On the New wire harness there is a blue and gray wire that I cannot figure out where it goes.

Do you have any idea why the reverse light stays on?
Expert:  D. Smith replied 2 years ago.
Well, since you've replaced the wiring harness, there aren't but about 3 other things it could be...
The Gear Position Sensor
The Digital Display
My best guess would be the Gear Position Sensor, but I've seen the digital displays get a solder joint bridged in them from a short in the wiring harness before also... The best way to troubleshoot the ECU is just to replace it with a known good unit.
Hope that helps!
