Question:
I am towing a 2011 GMC Sierra behind a 2006 Country Coach. Do you have a wiring harness that allows me to activate the tail lights on the truck through my Coach trailer light plug?

Expert Reply:
Yes, we do have tow bar wiring harnesses that will activate the lights on your 2011 GMC Sierra and plug into the connector on your RV. If the RV has a 4-Way flat connector you can use diode kit # RM-154. If the RV has a 7-Way trailer connector you can use diode kit # RM-15267.
We also have Hopkins harness # HM56101 which plugs in line with the vehicle wiring as shown in the installation video I linked for you. If you go with this harness you will also need extension # HM47115. If the RV only has a 7-Way connector you can use adapter # PK12716.
