Maybe you should give the chassis mfg a call for location if no one here can help.
Most I have seen are left side of steering column mounted under dash or maybe just tucked up in dash wiring area,

Should be one back at the engine. If you have an Allison I don't believe you can change the shift points. Might be wrong.

i did find a 9 pin gray plug with a twist on cap on the end of it just to the left of the steering column. I hope it is it as i am tired of looking........ Thank you for the reply

You found it, should be another identical one on the back of the engine also. You can do the engine, transmission and ABS brakes all through that same connector.
