I had the same problem! I ended up shaving some of the plastic inside the switch housing to allow the non switch side to pass through. It was a real pain but the part that I shaved off wasn't necessary so everything still fit correctlyI am trying to install the OEM grips - but my Switch did not come installed into the Switch Housing. Has anyone else seen this? Do I have to cut the wires, or De-Pin the plug to install into the switch housing? THANK YOU!
