1995 Dodge Ram ABS and brake failure lamp on

95 RAM 3500 single cab dually ABS light and brake light is on, checked all of the obvious and read about the rear ABS sensor failure replaced rear sensor, disconnected battery 5 minutes reconnected; both lights still on. Heard about possible jumper wiring problem connected ohm meter at front connector (body to frame under left front fender liner) has same ohm value as at the sensor. Wondering if anyone has wiring diagram so I can continue to test further or does anyone have any other suggestions. I am very familiar with diagnosing however without a schematic or wiring diagram it is almost impossible any help would be greatly appreciated thanks! I also have another 94 RAM 3500 with the exact same problem
