The 550 fan GSX does not come with an accessory plug. I ordered the part from my dealer, expecting to get the wiring as well. The only thing in the package was the plug outlet itself. There were no wires. The instructions mention that there is a black wire and a red/yellow wire on the main harness and I should pull them out and connect them to the 12V outlet. Does the 550 fan GSX have this harness? If so, where is it located? Has anyone completed this install before? If so, where did you choose to install the accessory plug?
