have passenger side airbag from a 97 jeep XJ, got it at pull-a-part, it has four wires, two on each side, guessing one to each detonator, pulled the exploded one from my 98 but, it only has two wires to one side of airbag, one detonator i'm guessing, are these interchangeable, yes i know this is a dumb question, :-), but i've spent every penny i can spare, i'm on a fixed income, just hoping against hope they are interchangeable or modifiable. driver side same, gonna get the module reprogrammed, would be grateful for any tips or suggestions.
