BCM
Location
the BCM is located by the drivers left foot.
To Remove BCM its advice to, you have the Top down and if you remove the Driver Seat (2 Nuts and 2 Bolts), take the 2 bolts out that attach the BCM to the underside of the kick panel and then remove the wire connectors. Easier to get to that way and at least you can see what you’re doing. Reverse the procedure to reinstall.
