Passenger Presence System-B0098

[2003 Chevy Silverado]

I have a 2003 Silverado that I recently bought. The previous owner put the incorrect seats in the truck. The connections don't match up. So, I found a deal and got a set from a 2004 Silverado. I installed them and found out I still had a connection, from the truck, that didn't have anywhere to connect to in the passenger seat. All the passenger seat had was a big block with around 10 wires going to it. But the truck has another connection with 2 wires going to it. The seat doesn't have any other connections going to it. So I have the Service airbag light on. The error code is B0098. I have searched and searched and even went to the nearby Chevy dealership for answers. No luck! I mainly just want to know what the 2 wire connection goes to and what replacement seats my truck is supposed to have. Any way to swap harnesses or any other options that someone has found to fix this problem? I'm tired of putting so much money into these seats and I need the airbags to work. I've tried replacing both impact sensors, airbag disable switch, followed every wire to make sure they are all in order. The obvious problem is the 2 wire connection that has no where to go to. Maybe the seats I bought from the 2004 Silverado had that feature already built into the seat?
