Parts Need for Installing a 7-Way in the Bed of a 2008 GMC Sierra 2500HD for Fifth Wheel Towing

Question:

I have a 2008 GMC2500HD Duramax crew cab 4x4 that has the trailer towing from the factory. It has a bumper plug for the trailer installed and wired. I was wanting to install a plug inside the cargo bed for a fifth wheel and i am looking for a complete harness and plug to mate up with my existing wiring. I want to able to keep both plugs hooked up so i am able to tow either a fifth wheel or pull a trailer. What part number am I looking for that would fit?

Since your 2008 GMC Sierra 2500 has a tow package, you would use part # 31156 to place wiring in your truck bed for fifth wheel/gooseneck towing. You would also need an in-bed 7-Way like part #20027.
