Expert Reply:

It sounds like you have a standard trailer 4-Way but that there are multiple wires coming from it for the various functions (like 2 running light wires and 2 ground wires as an example). For your application I recommend replacing your 4-Way with the Hopkins Easy-Pull Harness # HM48114 and making your connections per function with Heat Shrink Butt Connectors # DW05744-10.

The wiring on the Hopkins connector is labeled so you just need to make sure the functions match up and you'll be good to go! If you have something else that looks different just let me know and I'll be happy to further assist. Unfortunately we don't have a 4-Way flat with 7 wires out the back of it.
