Convert your SAE (Battery Tender™, Yuasa™) lead to accept a heated clothing controller with coax connector.
Battery Tender SAE pig tails are usually 18 or higher awg with a 3 amp fuse (if any).
Mostly okay to run low draw heated gear like gloves but if you want to run higher amperage gear, you need to change out the pig tail for a higher rated 16awg 15amp version.
You can also use this adapter to power older SAE gloves direct from modern coax heated liner sleeves.
Adapter is 9 inch long.
Wire is 16AWG
