Trailer Wiring Harness Recommendations for a 2003 Buick Park Avenue

Question:

I will be purchasing a wiring kit and a trailer hitch for my 2003 Buick Park Ave. I am confused about which wiring kit I would need. I have not purchased my trailer yet, but I assume it will have LEDs. Which wiring kit do I need?

If the trailer that you tow does have LED lights then using wiring harness # 119178KIT will require the least amount of installation time since it is a non-powered converter. This means that the trailer lights will draw all their power through the vehicle tail light wiring on your 2003 Buick Park Avenue. This is perfectly fine though since LED lights draw such little power.

But if the trailer has regular incandescent lights or you ever need to tow a trailer with regular incandescent lights I recommend going with a powered converter, # C59496. It requires a direct connection to the vehicle battery to power the trailer lights so the vehicle tail light wiring does not get overdrawn.
