Just got my motortrike adventure kit installed on my 2012 gl1800. The trunk open warning for the trike trunk does not work. I questioned the installer on this and was told the plug was changed for 2012 and will not work with the motortrike plug.Can anyone with a motortrike kit verify this or am I not being told the truth? I will get this working on my own this fall or winter,after riding season, looks to be a simple fix.
