Some second gens came with the plugs, some did not. its not hard to wire them up though, a simple google search will yield the results you are looking for.

 

Ok so I can't sleep so I figured I'd do a little research.
I have a 10/97 built 98 blazer Lt I'm picking up a new set of Bravada seats which has full power passenger as opposed to my blazer which is just power lumber in the passenger side ! Also driver side has a memory setting for two drivers!
Anybody know anything about these seats and if they will plug and play?
Thanks for the help
