The 95-96 modules are totally different from the 91-94s. The brake lines and wiring are different, as well as the mounting bracket. The wiring for the 95-96 comes from the engine harness and attaches to the unit on top with a large connector. The 91-94 wiring comes from the fender harness, and connects with an internal connector. I just pulled a system from a 96 for someone, and shipped it to him. Someone removed it from his car, and he wants to reinstall it. He lives in the snowy north, and it may be good for him. Package weight was 17#.
I have not driven a 95-96, and used the antilocks, but I do know that I do not like the 91-94 antilocks. I have disconnected them on my 91, and do not miss them. I may disconnect them in my 92 as well.
