Finished all off today.
Very easy to do once I found all the right connections.
All working and nothing needed to be enabled in the PCM.
Only issue I had was that the gears had stripped from the seat motors that control the height of the base. I removed the one from my standard interior and fitted it to the leather seat and it works a treat. Just need another one to mod for the angle adjust for the base. I'm not paying a fortune for brass gears.
