Hi,

Can anyone tell me what this button is in my 2020 Chevy Tahoe PPV? And how to use it? Is it secure idle?

Also, the Rear Park Assist button lights up but there is no audible warning. Is there a way to enable this?

I just bought the car. Really interested in OEM swapping leather front heated seats, leather heated steering wheel, automatic power running boards, and Silverado jumpseat. Wish I had guidance on these upgrades and how to get them working.

Where can I get wiring harnesses for my planned upgrades? I emailed cmatt but got no reply. Thanks.
