Overall excellent service. Price was right, shipping was fast, and the products were as advertised. Two minor quibbles: Packaging could have been better as the hitch arrived with one end poking out of the box. No significant damage though. Also, the installation time estimate 30 minutes was a little optimistic unless you have air-tools. Took me about 90 minutes doing it alone on the ground. The directions were clear and correct.

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

The wiring system on this vehicle is not strong enough to support both the vehicle and trailer lights. A powered converter or Modulite is required. 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.

etrailer.com recommends the Circuit Protected Powered Taillight Converter with Installation Kit (# 118176KIT) 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.

Choosing the Right Wiring Harness

In order to choose the correct wiring harness for your vehicle you first must know how many lights are on the trailer you will be pulling.  The number of lights determine the number of amps that the trailer is going to be drawing from the vehicle's wiring system.  Standard Taillights usually require 2 amps per light.  Clearance and Reverse lights take 0.5 amps per bulb.  Some clearance and reverse lights have 2 bulbs.
