So what was included in the tow package? The only one I've found on the Mopar site was a full harness that required drilling holes in the jack box and wiring to the taillights plus two circuits to the battery. Lets assume that the connector contains Right & Left Turn/Brake lights, Tail Lights, Backup Lights and Brakes and that you get ground from the frame or no brakes and it has ground. Does it connect directly to the plug or does it wire to a controller then the plug? How much can it drive?
The Factory harness from Mopar looks like it contains drivers for the lights, aux power and a brake controller all connecting to a 7 pin connector so nothing else is required.
Need more information.
