I can say the wiring kit is a huge waste of money. For $29 bucks I basically got a power cable. The kit has a very short black ground wire and a written statement saying on motorcycles you must ground to the battery.
No way can you reach the battery with the supplied ground cable. The rest of the kit is a few zip ties and wiring connectors.
I laugh cuz all I used was the fuse holder. I had power and enough ground wire from a previous install as well as speaker wire, but my kit was only $11 on ebay.
