Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. This part uses male terminals with 16 pin connections, so matching the original electrical interface is important for proper fitment. Confirm the truck is a 2013-2018 Ram 2500 or 2013-2018 Ram 3500 before ordering the DFIP4.
