I see, that makes sense. I apologize for the bad questions. Could you explain where I would find the power wire? Is that the wire that is connected to the BAT terminal on the distributor? Thank you for the info in regards to the "shelf life" of the module. I was told that a lot of these NOS parts do have shelf lives so I was questioning as to whether I shouldn't have gotten an NOS unit and just went to Autozone and picked up one there. Thanks everyone
