I had an electronics dealer install a compustar brand remote start on my 2015 eco that works flawlwssly and you can use it with your regular factory remote. They have a module with a wireing harness that doesn,t need to have any of the factuary wireing cut into. Only 1 wire needs to be soldered to a hot wire that is always hot. It can be programed to run longer than the factory remote start. I have mine programed to run for 30 minutes. you hit the lock button 3 times to start the truck. It cost me about $450. I had an estimate from my dealer and they wanted about $675 to install factory equipment and I thought he was giving me a snow job. He told me they have to take out the rear interior ect.
