A factory 6-Way is certainly not all that common but it will have a brake output circuit and plugging in a brake controller will work. But there may be some connections that you will need to make under the hood to make everything fully functional. I have included a link to our FAQ article that covers the under hood connections that you will need to perform if they are not completed already.
Please note that on a 6-Way trailer connector there are 2 ways that it could be wired. The center pin will either be the brake output circuit or the 12 volt circuit. You will need to make sure the adapter and trailer side connector are wired the same as the truck. Otherwise what will happen is the trailer brakes will lock up and stay that way because they would be getting 12 volts all the time. Rewire the connector/adapter as needed.
