I just installed a dball2 remote start I picked up on eBay in my 15 2500. Easy install. Took maybe 30 minutes tops. I was going to go with the oem, but the extra cost of the flash was a killer. I didn't want an extra remote, so I went with this one. Push the lock button 3x and she starts right up. I recommend it. I purchased 2 kits for 245 shipped. One for my ram and one for the wife's grand caravan.
