All ABS units are designed so that if there is a failure the brakes will continue to function, you just won't have ABS.
The mazda pickups have RWAL (Rear Wheel Anti-Lock). The reason for this is because the rear end is light and the rear brakes engauge first, since it is so light they tend to lock up. Mazda put RWAL on these trucks because when the rear wheels lock up and the fronts don't the rear end tends to try to pass the driver and cause a spin out.
If you bypass it all your brakes will work fine just be careful during an emergancy stop, I would try to put some wider tires in the back or transfer some weight back there to help conpensate.
