Trailer wiring kit comes with a 1 year warranty and everything necessary to install the trailer plug wiring. Tekonsha manufactures a wider range of different products for hooking up trailer lights to your Car Truck or SUV. T-One connectors work great with boat trailer wiring and utility trailer wiring. Typically those trailers will use the standard 4 flat plug which is what our T One connectors offer. If you have an RV Fifth Wheel or any other large type of trailer you will us a 7 pin trailer plug to control your electric trailer brakes. Tekonsha offers 7 pin trailer connector as well. Simply do a search above to see if there is a 7 wire trailer wiring available for hooking up your 7 way. If there is not you can use part number 85343 trailer wiring adapter to convert any 4-Flat into a 7-Way. In addition you will use part number 20506 which will include the rest of wiring needed for electric brake controls.
