ABS Light on and ABS dont work no more!!! All since SR Swap!!!

[DanielIser]

I have a 91 240sx with a sr motor swap. The car has HICAS also. My abs light comes on as soon as I start moving forward in the car. Any idea what it might be? This happend after the sr swap. Also the car doesnt use the abs, as i know this from experience. b4 the swap i have never experienced what it felt like to drive on tires with flat spots and I know this feeling now!!! Is this a common problem because i cant find it in search.

you prob have some kind of interface between abs module and something else to hook up. what? i dont know. all i can tell you is that there may be some more wiring in your future. actually, here is a wiring diagram. do you have all this hooked up?
