Running Lights on a 2009 Mercury Mariner Stay on With Curt Wiring Harness # 56067- I spoke with my contact at Curt and he told me that the T-Connector Wiring Harness, # C56160, was improved from the older # 56067 wiring harness. The new # C56160 harness comes with an improved converter box to prevent any power from back feeding onto the vehicle tail light circuits.
This wiring harness will install the same way on your 2009 Mercury Mariner as the 56067 harness. I have attached a link to the installation instructions for you to reference.
