The brakes should not lock up unless there is a problem with the porpition valve in the abs unit itself. With the electri connection disconnected the abs system will not work, that means when you step on the brake it will not pulsate to keep you from skiding, that is what abs does. With out abs the brakes will work like normal brakes, if they do lock up the valves in the abs unit itself is not working releasing the pressure when you let off the brakes, I just did a 1999 blazer that did the same thing and Even after disconnecting the abs the brakes would grab, that was because the portioning valve in the abs unit itself went bad. You will find the abs unit if you follow the brake lines comming from the brake fluid resevior. It will have two lines going into it and 4 lines comming out of it.
