This is a short splitter cable that you can plug to the Battery Tender Harness with the old style SAE connector on it that many of the shops are putting on bikes when they are sold. It splits from the SAE to another SAE that you can plug the Tender into and a Coax Jack that will let you plug our Heat-troiller and Heated Clothing into. It Uses 16AWG wire so it is safe for a set of heated clothing.
Warning: If you are going to do this then swap the fuse in the Tender cable with the one you received with the Heat-troller battery harness, so it will handle the draw. You need at least 15A fuse in the battery harness.
