It is on the end of a battery charger/maintainer pigtail. It is already on the bike, so if someone could give me a heads-up on the brand, then I have one less thing on the to-do list for my K-LT.
I have several Battery Tender brand units sitting around, as that's what I've always used, and what I have my other bikes hooked up to, but this is different.
Thanks in advance for any help. Apologies if I posted this is an incorrect subforum; the most topical subforum for this question hasn't seen any activity since last July.
