You want to tow with your 2018 nissan pathfinder. Some pathfinder models include a factory wire harness, but many do not. If your vehicle does not have one, you must install an aftermarket wire harness. Using the right wire harness helps you connect trailer lights and signals safely. This keeps your towing experience secure and trouble-free.
Check if your 2018 Nissan Pathfinder has a factory wire harness before you buy an aftermarket one. This can help you save time and money.
Pick a 4-pin or 7-pin connector based on what you need to tow. The 7-pin connector works best for heavier trailers. The 4-pin connector is good for lighter loads.

Follow each installation step carefully to make sure the connections are right. Test your trailer lights after you finish installing. This is very important for safety.
