Thank you very much for the help. That fixed my problem.

ok i will give that a try. Thanks

The lift select button is on the left handle.
Same place as the horn button on the right handle.

I didn't read your post properly. Your truck is operational so all that needs to happen is a configuration download as I described.
Hold both deadman down. Key on with right hand and use left to push lift select 3 or 4 times before the truck starts selftest. Some guys just keep pushing the button fast. There is some timing to it but it's not like the pedal dance on a cat or anything.
You'll get it.

Yes, I am very familiar with sa/sb 96/9700 537 589 and TRT.

I didn't mention that you have to keep the deadman pedals down.
Push lift select button 3 or 4 times within 3 or 4 seconds.

If this does not work unplug the bus cable from the display interface card and see if it drives. If it does you need an interface card.

I did this but nothing changed. Also this is a Turret Truck so i did all but push the button i hit the lift switch 4 times but made no differance.

Try programming the display.
Step on both deadman. Key on and push lift select button 3 or 4 times, this will run configuration download. It will code 57. Turn off then try to drive normally.
