I've read some older posts on this subject and have a few questions about the upgrade to the Speedo/Tach gauge 74745-08. I've read that some members have had trouble with the gauge breaking down, Are there problem with it ? As far as installing it a member said they had to splice the wiring to the gauge cause it was to short to plug into the new gauge, I thought these were plug and play ? Can this be self installed with out screw up the ECU in the bike or will need to be dealer installed ?

Thanks
