ABS light on, no speedo

I'm back.didn't mean to blow you off but Had to go out of town, family stuff. We are running 31's and were thrilled to hear that the Psom could be calibrated to reflect the larger tires. No more guessing or being pulled over. No ticket, but warned that the tires were throwing my speed off. Nice police officer. Btw the tranny fluid and filter change didn't do anything about the whine. Sounds like a pump going bad? We have other priorities so we will just drive it .

It is my understanding that the PSOM's are the same throughout the years although 95 got an improved version.
I also think the trucks and bronco's use the same PSOM.

The differences between years happen in the cluster assemblies.92-93 same, 94-95 same, 96 not sure.
The early clusters cause charging problems in the later trucks.
