Default Bypass ABS?

1989 , Auto. is there any information on performing an ABS Bypass? -vs removing the whole unit. It's got to be serviced, but I'm not positive of the process. Trying to get my tech as up to date as possible.. Thank You!

Are you asking how to remove the unit, get it serviced and put it back? Or, remove it and bypass it for good?

You basically need to fashion a couple of lines to connect the inputs to the outputs of the abs unit. The lower lines are inputs, and the upper lines are outputs. The passenger side is for the rears. Connect the lower line to the upper. The drivers side is for the fronts. You need a tee to connect the lower line and the two upper lines all together. All of this is under the compartment behind the driver's seat (or under the speaker behind the driver's seat in a convertible).

Here's a thread with some pictures and an example where someone added a proportioning valve back there.
