I'm not sure about the answer to your question John as I have surge brakes on my boat trailer. I always understood electrical brakes required the 7 pin connector and did not think anything else was required.
The following is what I discovered in the owners manual - hope it might help.
Towing Requirements – Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
The Trailer Tow Package may include a four- and sevenpin
wiring harness. Use a factory approved trailer harness
NOTE: Do not cut or splice wiring into the vehicles
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.
Next illustrations in the manual show 4 & 7 pin connectors and wiring connections.
