Clueless I am about auto terminology; nevertheless, I'll be grateful for some input, please. I want to attach an OBDii connector to the OBDii port in my 2006 Honda Element for the purpose of making active the 12w "cigarette lighter" receptacle. The reason for this is enable plugging in a solar battery maintainer/charger instead of attaching the charger clamps to the battery posts. Doing that every evening during a Wyoming winter is an enormous pain. My question is: has anyone out there done this and are there any pitfalls to be avoided? I have the charger-specific OBDii connector and I have the Element, but I don't have the local mechanics' know-how on how to do this.
