OK, I went outside last night, sat on the ground and kicked and screamed like a spoiled 4 year old who didn't get his new toy at Wal-Mart. Went to bed and am now having coffee. I feel much better now. I apologize for my previous outburst. Besides, who am I kidding, I don't anything about horses.
So, I'm going to take some time to figure out the wiring for the ABS, and how it works (the voltages applied, type of solenoids/valves used...not how ABS works). Maybe I can find a way to cycle the CAB without a DRB.
Anyone have a pinout for the CAB connectors, or better yet a schematic?
