So... been reading all the posts and I think your harness can help me if I buy a 2018 Module. I have a 2017 sierra and previously tried to remove the little sticky piece from the original module. It would charge my Iphone 8 but it was sporadic so I gave up. Now I hear if you remove the little magnet as well it will work. Any insight into this? I guess my other option is to buy a new module and the wiring harness you created. If so, it is still available?
