I've been working on stealths for a couple years now, and have a DRB II with all I need for 1st Gen stealths. Just started working on 94's and my DRB will not connect to the underdash diagnostic plug. Did some research and I believe I need a "y" cable? Does anyone know where I can get such a thing, or what the part number is so I can search ebay? Well I found what I needed. You require a 16 way adapter, and to make a DRB II work for 2nd Gen Stealths, you also need a 1988-1994 Yellow Supercard.
