4-Pole Trailer Wiring Harness for 2014 Audi Q5
Question:
Why use a Curt 56190 light connector as opposed to a Curt 56200 and when is a CURT 55151 powered converter required. I am so confused

Expert Reply:
Trailer wiring harnesses are offered in both powered and non-powered types, as you note. Powered converters offer the advantage of better isolation of the trailer lights' current demand from the tow vehicle's wiring. Non-powered harnesses use the tow vehicle tail light wiring to deliver the actual current needed by the trailer lights. In some cases this could lead to overload of the vehicle's wiring.
For your 2014 Audi Q5 I suggest the powered converter # 119250KIT from Tekonsha. This will provide high current capacity for your trailer lights without risk of overloading your vehicle's wiring. The linked instructions and installation video will show you how this unit installs. The kit includes a circuit tester to help you identify the functions carried on each vehicle wire. I suggest you also use a 4-pole mounting bracket # 18144 to hold your trailer connector securely at the rear of the vehicle. Mounting hardware is included.
