Learn how to hook up a trailer safely. Verify ball size, chains, wiring, and coupler setup with this quick guide from On The Go Trailer Rentals.
Hooking up a trailer seems intimidating the first time, but it’s actually simple once you know what to check. Here’s the exact process renters use with our fleet.
Before connecting anything, confirm that the hitch ball size matches the trailer coupler. Using the wrong ball size can cause the trailer to disconnect while driving, making this the most common and dangerous mistake.
Raise the trailer coupler using the jack, then slowly back your vehicle until the hitch ball is centered beneath it. Proper alignment makes connection safe and easy.
Lower the coupler completely onto the hitch ball, then close and lock the latch. Insert the safety pin or lock to prevent the coupler from opening during travel.
Connect the safety chains to your vehicle’s hitch points and cross them underneath the coupler. This adds backup security if the primary connection fails.
Connect the trailer wiring harness to your vehicle to activate brake lights, turn signals, and running lights. Always test the lights before driving.
Set the brake controller based on the trailer’s weight and load. Proper adjustment improves braking control and helps prevent trailer sway.
