Does the Power Wire of the Tow Ready Wiring Harness for 2014 Honda Accord Need to Run to Battery

Question:

An installer said that the hot lead on the trailer harness does not have to be connected to the battery because I have a small trailer with minimal lights and that it will not cause a problem. Is this accurate?

I can only recommend what the manufacturer of the Tow Ready Wiring Harness # 118596 recommends for routing the power wire, which is that you will need to route the wire to the positive side of your vehicle battery.

The purpose of routing it to the battery is to protect the delicate wiring of your 2014 Honda Accord. In the event of a short on your trailer, even though it has minimal lights, this added protection will ensure that you would not damage the wiring of your vehicle. This could potentially save you a lot of money in repair bills as the wiring in newer vehicles is pretty complex. We personally see a lot of blown fuses and shorts on vehicles that do not run the power wire to the battery.

Most likely your installer just does not want to deal with the hassle of routing the power wire all the way up to the battery.

I attached an FAQ on running the power wire for you and your installer to check out.
