Question:
I am looking to add both a 7 pin for a camper and a 4-pin for a plain trailer connector to my VW Atlas SE V6. I found the Hopkins 40920 which looks like the functionality I want, but it says it does not fit my Atlas Is there a similar product that will fit my vehicle? Thanks

There are a few different items you will need to get electric brake functions for your 2019 Volkswagen Atlas.
First you will need The T-One Vehicle Wiring Harness # 118754. This harness will give you the 4-flat connector and make it to where your trailer's stop, turn, and taillights mirror your vehicle's stop, turn, and taillights. This harness plugs into your vehicle's wiring harness, which is located in your rear cargo area.
Next you will need The Universal Installation Kit for Trailer Brake Controller # ETBC7. This connector will plug into the 4-flat connector mentioned above and gives you 4 additional wires that you will have to wire up there functions are below:
Black Wire - Connect to battery with fuse or breaker for 12V power source
Blue Wire - Connect to output wire on brake controller
White Wire - Connect to vehicle frame for ground
Yellow Wire - Auxiliary wire for 12V power, reverse lights, or reverse lockout for trailer brakes
Finally you will need The Redarc Tow-Pro Liberty Brake Controller # RED24FR and The Universal Wiring Harness for Redarc Tow-Pro Trailer Brake Controllers # RED69FR.
The controller mounts out of the way under the dash and the control knob is on the dash giving you a factory look. Giving you the power to control your braking power with the turn of a dial and manual override right at your fingertips. The universal wiring will plug into the controller and the other end splices into your vehicle's wiring.
I attached an installation video link below.
