Hello all.
Recently bought a 2011 Ram 3500 that has an edge insight cts2 monitor on the pillar and a knob on the console with 1-5 on it. Looking under the dash there is 2 things plugged into the obd plug. One goes up the side to the insight and the other goes over towards the console with the knob. I haven't had time to take the console apart and see if there is anything else there besides the knob. I haven't messed with much but from what i have I cant tell a difference when i turn the knob. The truck was a trade in at a local dealer so I dont have a way to ask the previous owner anything. Just wondering if anyone can tell me where and what to look for to figure out what i have. This is my first diesel pickup so i dont know anything about all this.
Thanks in advance if anyone can tell me anything
