Has anyone finished with installation of this, please? I'm planning to do same in my Custom 2020. I already purchased recommended power inverter (https://www.amazon.com/gp/product/B01KT26D68/ref=ewc_pr_img_1?smid=A3W15S426VVWJO&psc=1) and I also got OEM Power Receptacle for the dashboard (https://www.gmpartsoutlet.net/oem-parts/gm-jet-black-accessory-power-receptacle-84581301?origin=pla&gclid=EAIaIQobChMIu9-QmZm-_wIVUMOGCh1djwetEAQYASABEgKq7fD_BwE) I'm planning to splice power from 12v socket to feed that tiny power inverter. This is the simplest workaround I've found all over internet to avoid BMC charges. Sadly, it will keep power running constantly for as long as the truck is ON, but it is what it is... I would appreciate any help from members here. Thanks!
