Will Pollak 7 to 4 Pole Adapter Work On 2009 GMC Sierra With Factory 7-Way


Will this product do the electrical as well as the physical conversion of the separate brake/tail lights on my 09 GMC Sierra 7 blade factory RV connector to the 4 wire flat connector on my trailer. Desired end result: Plug adapter into the truck, plug the trailer into the adapter and have both tail and brake/turn lights on the trailer?


Expert Reply:

Yes, the item you selected, Pollak 7 Pole to 4 Pole Adapter, part # PK12716, will work great to convert the 7-way on your 2009 GMC Sierra to a 4-way.

This adapter will allow you to do just as you described; plug part # PK12716 into your truck, plug 4-way trailer connector into adapter, and have functional lights on trailer.
