hello everyone,
a coupple of weeks ago my shitty tan seats in my B5 started to take on the drivers side. im so pissed off but now i cna take advantage of this and get the s4 seats i have always wanted. i have a coupple questions i need help with before i by the seats so i can make sure that i will have a smoth transition in changing the seats.
1. is it hard to install these seats and does any modifying need to be done>
2 what do i need to get power to these seats? my current seats are heated but not powered?
3. the person im buying these seats from doesent know if the seats are heated...is therea way to check like extra wires or anything like that?
