Sure would be a good hack to get part numbers & cross reference what vehicles use these parts,comes in handy if something breaks on the road you grab that part from that old Massy Ferguson to back up & running.
A 12v meter would be a handy item to have in or on the dash. You could go through the frunk access panel with a DVOM periodically to check it’s health but to have a meter you can monitor may be a nice addition to help you from getting bricked if the battery dies.
