Okay, I need to report that I just had an issue with the scroll function quit working. Figured it was the mashed wire maybe had broke. So pulled the plug and dash, the WHITE wire had pulled out of the extension plug. Took a push pin and released the pin in the connector, soldered the wire in stead of the crimp. Good to go.
Just wanted to post a heads up, the extension may not be robust enough to stand up to running around on a bumpy bike. The original mod we spliced the CAT 5 cable into the switch wires and soldered everything. Not having the plug will require that you remove the switch from handlebar when you remove dash.
