How to adjust height on rethread style harness

If your Baby Jogger stroller seat has a rethread style harness please find attached how to remove from the back board in the seat fabric and then reposition on a higher or lower shoulder height. 

Please note it's essential when you rethread your shoulder strap that it goes through the back of the back board, not just inserting into the fabric, as it will pull through to the front when in use.
