If you're looking to buy OEM, Ron Ayers. http://www.ronayers.com/ . Use the Parts look-up. The Thumper Talk store has OEM and aftermarket. http://https://www.thumpertalk.com/shop/ I've also bought aftermarket stuff from Jake Wilson. http://www.jakewilson.com Or Alan, aka AB13, can probably fix you up. I got a cig lighter socket from Ace Hardware. It had alligator clips on it that I cut off, added wire to it, and wired it to the battery. Put an in-line fuse in the wire if you do this.
