I bought a 1989 F-Superduty rollback and have been going through every system on it. The truck was a total mess with nearly everything rigged or broken on it. I replaced the entire wiring harness from a 1991 donor F-250. Every thing works as it should now, but am wondering now if it is possible to add rear antilock to the truck given that it has rear disc brakes. There’s even a speed sensor in the rear end which to me would serve no purpose other than rear antilock. The only thing I don’t have installed yet is the antilock valve assembly that mounts on the frame rail. The truck even has the two lines capped off there from the factory. Does anyone have any info on this?
