No power to cab or ignition switch, new switch, new ground cable, plus new ground strap. Only place I have power is the starter alternator and ABS module because the three feed from new battery. Nothing when you turn the key no lights horn dash power nothing at all.

Follow the smaller battery positive wire to the fuse box and check that connection. That is a real common cause of the symptom you described on all brands of cars. To verify that, turn something on in the vehicle so current is trying to flow, then measure the voltage on the terminal on the end of that wire. You'll find 12 volts there. Next, move the probe a quarter inch to the stud that terminal is bolted to, and you'll find 0 volts there. Those two readings are supposed to be exactly the same since they're the same place in the circuit. When you find any difference in the two readings, clean and tighten that connection.
