This is some good information regarding the power seat setup.
I bought a '98 Trans-AM driver seat for cheap last winter and installed it in my '87 Cutlass.
It has full power with power lumbar but I have not got any of it hooked up.
My driving force for switching to the TA seats was after I ran my car at a local SCCA Solo II competition. Those stock buckets didn't do anything for support and I practically had the center console riding up my crack the whole time. LOL
Here's a pic of mine:
How did you get the power lumbar hooked up? I assume there is an electric pump for this?
Thanks,
