The PO had cut all of the connectors to the ABS and in the process cut a ground. It was tucked in the ABS wire loom where I couldn't see it. I removed the ABS unit, installed brake lines and a proportioning valve from a rwal truck, left off the abs, then grounded that ground to where the abs used to be and now everything works! I also pulled the dash out to help track down the problem, and from what I found the only ground in the cab was close to the obd connector. The HVAC grounds ran out of the cab into the engine compartment from what I could tell. I am very happy and thanks for the help from everyone.
