Starting to do some major work on my 2000 ram 1500 sport. Wanting to clean up under the hood. Want to remove abs and put in an adjustable proportioning valve. Rear wheel speed sensor runs through cab module before going to pcm. Speed sensor is just a square wave form. Was wondering if anyone knew if it just sent the same wave form to pcm for speedo and shift or if the cab altered the wave in any way first. I am going to scope in and out at the cab module but was just looking for some insight first.
