This is the model specific MACH2 harness for your 2011-2021 Dodge Ram 1500-3500 non-360 camera truck. This harness, paired with our MACH2 package, allows you to view up to four cameras on your in-dash monitor. This is a replacement part for our MACH2 kits and is essential for operating our MACH 2 system with our interface box. Purchase this only as a replacement part since the camera and interface box is NOT included, or to mix and match our MACH 2 kits.
