I recently bought a '04 V70 that had rear end damage that was repaired and a new hatch installed. Unfortunately, the guy who installed it must have crossed his wires
as the hatch will be locked when all the other doors are unlocked and vice versa. It is comical to have to open the drivers door, lock the car and then open the hatch,
and then re-unlock the car. If the car is locked (hatch unlocked) and someone opens the hatch, the alarm goes off!!! Presently, there is no way to have all doors and
hatch locked or unlocked at the same time. Any help on a re-wiring solution or will this be too tough for a DIY?
