Line up the tow ball with the trailer hitch

It may look like this in your reversing camera

Make sure your hitch is free to drop on to the tow ball.

Wind the jack to allow the hitch to drop on to the tow ball.

Ensure hitch is locked down, you can see how it looks different to step 3

Secure the jack - on this trailer the wheel is stored facing up not down. Ensure the jack is locked into place and isn't loose that it can end up dragging on the ground.

You hitch will most likely have a hole for a pin - put a pin in this hole to prevent the hitch coming undone

A padlock to prevent tampering while away from the boat and to help prevent theft of the trailer

Attach the safety chain - if you have two chains, cross them over

Ensure the pins for your plug are clean for a good connection

Plug the plug in and make sure it is secure,

If you trailer has a breakaway cable - the curly one - secure this to the vehicle.

You need to check the lights. If alone - you can set your phone up and record the left and right indicator and brakes by recording a short video.
