This powered converter adapts import and domestic vehicles with separate turn and stop lights (3-wire system) to standard trailer tail light wiring (2-wire system). The unit is powered directly from your battery, elminiating the current draw from your vehicle's stop/turn light circuit. This protects your vehicle's sensitive electronics, ensures that sufficient current is available to the trailer, keeps the trailer lights burning bright, and allows vehicle bulb-out detectors to function properly.

This 4 Amp unit is CURT's light duty model. It is ideal for light duty trailers. Trailers with running lights and additional lighting should upgrade to either the 10 amp or 20 amp version.

This unit is manufactured with Surface Mount Technology to ensure the longest product life, brightest trailer lights, and better mechanical performance under shake and vibration conditions that are common during towing.

Calculating Your Current Requirements:
You can calculate your trailer's current requirements using the following approximations. Simply figure out how many of each light type you have and add up the total current draw to select which model you need.
-- Each stop/turn light pair: 2 Amps
-- Each tail light pair: 1 Amp
-- Each pair of clearance/market lights: 1/2Amp

-- Compatible with LED light systems
-- 3 to 2 wire conversion
-- Input Connector: Splice-in
-- Output Connector: 4-Flat Vehicle End Connector
-- Power Connector: Spade Connector
-- Load Capacity: 4 Amps
-- No HD flasher or converter required
-- Separate power circuit eliminates current draw from taillight circuit

The converter was easy to install and works well. All electrical connections are well marked. The kit includes sufficient hardware and the trailer lead is a generous length making trailer hookup easy.

Took awhile to tap into the wiring harness, but after installed, worked great.

This unit worked well on my 2003 Infiniti G35 with LED taillights. The instructions are clear. It does not come with the necessary 10ga wire to run from the trunk to the car's battery. I had to run out & buy that separately. The wire running from the car battery to this unit MUST be protected with an in-line fuse. I made the mistake of temporarily connecting it up without a fuse, intending to get one next time I went to the auto parts store. BIG mistake. The wire shorted while driving, could have caused a fire &/or damaged the car's electrical systems. Fortunately it didn't, but please learn from my mistake.

The mechanic I used to install my hitch actually teased me that what I saved by buying a hitch on the internet, the guy made it back by selling me the fancy electronic converter. He suggested he would just hard wire a flat connector into my wiring. An hour later he called me admitting, "Your guy knows his stuff ... the car's wiring isn't powerful enough." My HitchSource representative saved my frustration and problems.
I was thoroughly impressed with the solid construction, paint job, and general quality of the Curt Manufacturing hitch.
Additionally, HitchSource got it to me in 3 days as promised.
They know their business.
