In Bed 7 way And 4 Pole Connector For A 2021 GMC Sierra 2500


I do speak Greek but I’m left in the cold with this work around? The directions as presented on etrailer did me absolutely zero good. Now in another language that I’m a little more familiar with ENGLISH where does this fine piece of equipment go 119190 and how do I install it using my in bed 5th wheel 7 point plug? Need a little help out here?

I'm sorry for the troubles you're having but I believe I have a solution. The Upgraded Heavy Duty ModuLite Circuit Protected Vehicle Wiring Harness with 4 Pole Trailer Connector # 119190 you reference, is meant to added to a vehicle that doesn't have a 4 way trailer connector already, and since you mention you have a 7 way, you should have a 4 pole already.

IIf you want to just add a 4 pole, I recommend using the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness w/ 7-Pole and 4-Pole Connector # HM54FR. This will plug into the existing 7 way connector at the rear of your truck, and run to your truck's bed, giving you in bed access to a 7 way and a 4 pole trailer connector. Utilizing this harness will still allow you to use the 7 way at the rear of your vehicle.
