Expert Reply:

We do have all the parts you will need to create an adapter as we do not have one already for the connectors you are needing. First you will need the 5-Pin round Socket # PK11502 and the 7-Pin Round Connector # PK11700. Then you will be able to wire these together in the correct configuration using the image below and the Wire # DW04906-1 which is sold by the foot.

If you are needing a 7-Way Blade # A7WCB connector you will also need a 2 to 3 Wire Tail Light Converter # C56196 to separate the tail lights from the turn signals. This converter is designed to be used with incandescent lights and would also require 3 Resistors # P230004A if your trailer has LED lights.
