Expert Reply:
If you are trying to install a trailer brake controller in your 2010 Mercedes-Benz ML350 the parts you will need are the brake controller itself, such as the Prodigy P3 # 90195, our installation kit # ETBC7 and a 4-pole wiring harness # C59236 if you do not already have one. These three items are all that are needed to install a brake controller and 7-way trailer connector with all light and power functions.
