Pils! There are no stupid questions!
You should have received 2x leash attachments for your bar.
1 is the “backwards velcro program”, that is designed to be a loop you can pass around your spreader bar in order to attach the leash to the front of your harness, off the spreader bar.
The second is a piece of webbing with our logo on it with a D ring on each end. This is designed to be attached to the back of your harness on the handle pass cable. Simply eject the handle pass cable’s safety release and slide this onto the cable. Reset the safety and then attach the leash to the opposite end of the webbing / Dring set-up.
(The leash also has a safety release tab on it too to ensure you can get away from the kite if you have to. Be sure - somewhat obviously - to have this safety end attached to the D ring and use the clip on the other end to attach to your leash line on your control bar. This ensures you can access the release should you have ejected from the kite and need to also eject from the leash in an emergency).
