Your vehicle may be hardwired using the accessories below when a T-One connector is not available.

The wiring system on this vehicle may not be strong enough to support both the vehicle and trailer lights. A powered converter or Modulite is strongly recommended in all cases where the trailer has more than one taillight on each side. Powered converters (Modulites) are spliced into the vehicle's wiring system to get the signal, but the power for the trailer lights is drawn directly from the vehicle battery. This bypasses all the expensive electrical components on the vehicle and reduces the strain on the wiring system. Circuit protection further safeguards the vehicle and the module itself from mis-wired trailers. For more information see our wiring faq page and our table below.

etrailer.com recommends the Upgraded Circuit Protected Modulite with 4 Pole Harness and Hardwire Kit (# 119176KIT) for your vehicle. If your trailer has a lot of lights, see our chart at the bottom of the page to help select the wiring harness that will work best for your application.
