Sorry to bring this back from the dead. Been having battery drain issues with my 04 sierra 5.3 for 2 years now and can't find a solution. Changed out the BCM, no luck. Have sold the truck to my mom, but want to figure this issue out before I give it to her. Can you tell me where you got that battery terminal?? Looking to replace my ground harness and make my own, but can't seem to find one like yours. Thanks.
