We do have a 7-way trailer plug and junction box item from etrailer, part # HS381-9000, that includes 5-foot cord and plug. This item's wiring is configured as follows:

White (ground): 10 gauge
Black (12V power): 10 gauge
Yellow (reverse/auxiliary): 14 gauge
Red (left turn and stop): 14 gauge
Green (tail and running lights): 14 gauge
Brown (right turn and stop): 14 gauge
Blue (brake): 12 gauge

We also have separate components like junction box # 38656 and 7-way plug/cord # H20046 (8-feet) that you can combine if you prefer using ring terminals # 44-5310A and # DW05702-1.

Vehicle and trailer wiring colors can vary so it is always best to wire by function; please refer to the linked article for guidance in completing the installation.
