My D is automatic but has those empty plugs/jacks mentioned, in the engine compartment. I have owned it for six years. I was concerned about them. Talked to someone who told me that, NOT wanting to reinvent the wheel, John and his designers looked over existing wiring harnesses and found a Jaguar harnesss that did almost everything the D needed but left a few plugs/jacks with nothing to do, So that is what they used, and that left a few dangling!! Whether that is true or not I don't know! Most of the stories I see on here are of the above nature "I heard someone say" or "I read it SOMEWHERE but I can't find now", so I take it all with a grain of salt!! Murray Vin: 05962 Lic: DMC-XII
