If you have ABS all you might need would be a ABS computer from a traction assist car and the VMM module with the button(or the 97 console button). It's otherwise all prewired in the dash and engine compartment harnesses. I'm not certain however that the HCU is different or not as it isn't specified one way or the other in my manuals. There's a pair of additional solenoids for traction assist but it's possible they are present but unused on non-traction assist ABS HCUs.
But it's really not that effective of a system. It's off at any speed above 30, it doesn't cut engine power, thus it barely helps from a stop in the rain and doesn't help at all in snow. If you have traction lock or ever plan to it becomes even more useless.
