Buyer beware. Check all your plugs and connectors before you order. This looks a lot like the chord you need to run from a standard pig tail (off the battery) to the rheostat, but it is not. The red tip needs to be female to connect to rheostat.
I bought this by mistake (not RMATV or Tourmaster's fault) but I can't for the life of me figure out wtf this thing is for. Packaging says Battery Tender Adapter....so I can plug a battery tender to the jacket? The bike? I don't understand. My mistake, but why does this thing exist?
