hi first time post ive just bought an 07 st diesal and replaced the half leather heated trim with a red leather recaro trim i think out of an 04i bought off ebay now the front seats are coming on and off all the time no matter what you do with the switch and also the drivers seat belt warning light and beep is coming on when i have the seat belt on any help would be grate thanks

 

I'd say the wiring is different connections buddy, It might not be the case but on the 2004 face lift you can set the temp of seat heat, on pre 2004 it's just on n off. Maybe this is causing problems? Worth getting a wiring diagram off a few different year models??
But I'm just guessing mate

 

ok will do thanks for the help maybe il go see if an auto electrition can help
