2017 SR400 Self-standing Anti-Pooling System (APS) with carpet friendly pole foot

New to here so go easy on me. Also, new to Supra boats. I have a 2017 SR400 with the factory cover that pulls tight over the boat and has the strap that hooks to the tower. It also came with 2 legs (4 pieces) and multiple straps, of which 2 are white and the rest are black. I'm assuming the different colors means that it goes in a specific location. Where do they go and where do the buckled straps connect? Manufacturer calls them "Self-standing Anti-Pooling System (APS) with carpet friendly pole foot".
