Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.
Features:
Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located either behind the driver's-side and passenger's-side tail lights or beneath your car by the rear bumper.
Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

Great product, easy on, so far all working, a 30 minute instal. Your business supplies a valuable product for anyone who is not a wirenut, and quite frankly if you are a wirenut your a real nut if you don’t use this product. Thank you etrailer!!
Super easy to install. No cutting wires. Just plug and play and everything works. Very good product.
As described very easy to install plug it in done
The wiring harness was easy to install in my 2009 G6. Works fine.
Got hitch but u.p.s. did job on box. Hole in box where both frame braces went thru box. Parts bag broke only missing 1-3/16 bracket.
The wire harness works perfectly. Hooks right up. Only need to drill a small hole for a ground.
the wiring kit worked perfectly with a little coaching from you telling me the color codes for each function the harness is great and your install advice was even better your yhe best
Extremely disappointed. Pins were coming out of the connectors right out of the box, tried fixing with electrical tape, but they just kept wiggling out. Proceeded with the install, and after an extra hour and a half of troubleshooting and testing voltages and continuity there’s current flow to the connector, but there’s absolutely no power in the connector does not produce any lighting on the trailer. The connectors fit perfectly though so I guess it’s compatible with my car. It just doesn’t work. Complete waste of my time and money.
The tail lights still work so I guess the wiring harness is internally damaged. Fully checked all grounding appears to be good so item is just defective.
