So the connector attached to the neg post the has 4-6 colored wires just needs to ne unplugged or does one of those colored wires needs to be cut and taped up? If so what color wire? Thanks TommyMy 2019 Armada has had intermittent "no start" issues; the problem seems to be ocasional battery drain. My dealer just replaced the battery, and "depinned ECU Charge Control Circuit" whatever that means. My amp meter is now showing consistent 14V, when before it fluctuated between 10 and 14. What did they do and how will it help?
