Had to trike (Motor Trike kit) my 2008 GL1800 due to multiple knee issues. Now I need to install a witing harness for my trailer. I have the Kuryakyn harnesses (including the 5 pin to 4 pin for the trailer itself.) Has anyone seen an explicit "how-to" write up for doing this, including routing suggestions to get thru the trike conversion? I was going to have a local motorcycle shop do it, but they told me some of the connections work directly with the plug-in harness, but some connections have to be made directly to specific wires, so I lost some confidence with them. Anyone ever seen an article on this wiring? Thanks
