Wiring Color Code for Hopkins 7-Way # HM20041

Question:

Cable p/n HM20041, is the wire insulation color coded per SAE J2863, and will the connector fit my 2015 F150? This F150 has one of the three small trailer towing packages, I do not know which. Also, is there a 6’ version of this cable available? Thanks,
