Will this switch fit my TRX400EX and how do I confirm compatibility?

The JAVIK switch is manufactured to match the fit and mounting points of 1999–2004 Honda TRX400EX Sportrax ATVs. To be certain it will work, compare the OEM part number stamped on your original switch with 35020-HN1-000 and verify the connector pinout and handlebar clamp shape. If those match, installation is typically plug-and-play.
