How do you convert a 4 way Uhaul Trailer wiring to a 7 way trailer wiring you have a 7 way addapter that hooks to a 4 way you just need to know where to connect the other three wires?

Don't worry about the extra wires, the trailer with a four wire plug doesn't use them. The extra wires left over are for electric trailer brakes, a 12 volt power supply from the tow vehicle and a rarely used back up light or third brake light. The trailer with a four wire plug only uses the white wire for ground, the brown wire for the running lights, the yellow wire for the left signal and brake and the green wire for the right signal and brake.


Do I need to purchase insurance for a Trailer Rental?

How do you install a trailer wiring harness on a Ford Ranger?

Your best bet would be to call or go to your local auto parts store and tell them you need a "plug in" trailer wiring harness for your vehicle....these are very nice items and easy to install, as you just "plug" them into your exsisting vehicle's wiring harness. No need to "search out" for which wire goes where and no splicing of the wires either. They are more expensive than a "standard" wiring plug, but the "extra" cost is more than worth the "time" and headaches you will save!


How do you hook up trailer lights on a 1994 Jeep Grand Cherokee larado?

There are trailer light kits available on-line that contain an adapter necessary to connect the wiring. The adapter is determined by the make, model and year of your vehicle. Extra lights are also available should you need them. Instructions are available. Also the dealership where you are renting or purchasing your trailer will be able to help you with the hookup.


How do you wire a trailer connector for a 2003 Hyundai Elantra?

I have read that you need a "powered" wiring harness because the Elantra routes the tail lights through a computer that cannot handle the extra amperage necessary to drive a trailer's lights. A powered harness connects directly to the battery for power and taps the tail-light wires to control relays.
