Question:

According to the information on the fitguide there is a vehicle specific connector cable making it appear to be plug and play. The answer on another page for a 350d I have a 2016 GLE 350 4matic by Jon G is that it is not plug and play and would have to be hardwired. Is the answer just for a 350d or is my GLE 350 with a factory hitch good to go with the Prodigy P3 Code 90195-3066-P? Also, do you list the specific location around the steering column area that there should be a Mercedes connector to plug to the wiring adapter? Thank you.

The answer page that you are referring to was actually completed a few years ago and at the time nobody had a plug-in option for the brake controller. I had contact different manufacturers and they all said that it had to be hardwired.

Since then, as you have found, a plug-in adapter has been found so all you need to install the Prodigy P3 # 90195 on your 2016 Mercedes-Benz GLE-350 is the Plug-In Adapter # 3066-P. This is the option you can go with if you have the factory 7-Way. If you don't have the factory 7-Way then you will need to install the wiring kits # 119250KIT and # ETBC7 to provide you with wiring for the P3 as I highlighted in my previous answer.

You can find the connector for the plug-in adapter under your driver's side dash if you pull back the carpet that sits behind your brake pedal. I have attached the instructions for the adapter as well as a clip from the instructions that shows the steps you need to take for the install.
