Hello I have a 1993 f-250 7.3 nonturbo with a 5 speed manual. After changing my instrument cluster out with the one out of my 1993 7.3 with a turbo and a 5 speed manual. After changing it the ABS light is on. The old instrument cluster must of had the bulb burned out and I didn't know it. The light only comes on after about 5 seconds after you drive forward. If you let it sit there and idle it does not come on. Speedometer seems to work fine so don't know if that means the ABS part of the sensor is good. Checked the fuse and it is good.
