Honda TRX 1999 TRX 250 Recon — Add 12v Aux November 17, 2015 I recently acquired a pair of 1999 TRX250 Recons and would like to add a 12v port to run a GPS/charge a phone while on the trail. Is there an easy/recommended way and location to add a 12v aux port that functions well and looks somewhat OEM?
