Aux plug / heated gear / battery tender

[arthureld]

Hey guys,
I have a 2010 Ultra classic limited. I put it up on the lift today to detail it. I removed the side covers to just check everything out. I noticed a cable that looks exactly like the one I use for my battery tender and also for my Slime air pump. Is this for the Battery Tender or is it for something else. I hate to plug into it without knowing for sure.

It is for a battery tender.

I'm going to use it to charge my gps too but I'll have to find another adapter for that..

You might be able to find an adapter on this site, or from the site the powerlet link

Thanks boulderbean.
I ordered the SAE to cigar lighter adapter which will do the trick just fine. I have two batteries so I won't need it often, but it's good to have just in case.
