I am really trying to think how this would work.
I know the vehicles set up for paraplegics I had seen had a single lever that tied into the accelerator and brake. You would push forward to apply the brake and then rotate a lever that was about 12 inches long clockwise to apply the throttle.
I am just trying to envision the hand throttle, as it needs to be spring returned and it seems like it would get in the way.
The lever was operated with the right hand. I am wondering if you could mod that lever to operate with your left hand. Then you could steer and do the shift with your right.
Also put the lockup switch on the above throttle might simplify things.
Were you not planning on using a spring returned hand throttle Josh?
How bout this, I know there is a CORR off road racer named Evan Evans who is also Para. His Throttle and brake are on one right hand lever. You push forward for the brake and the throttle uses a twist grip like on a dirt bike or motor cycle. This way he can still spool up with the brake. As for the shifting, go with a manual valve body, use the air shift on a button on the steering wheel, you may even possibly rig up another air shifter on the reverse side so that you can hit another button and it will down shift. Only other thing that might be difficult is finding a full ratchet shifter, one that ratchets from park to 1st instead of a Gate/Ratchet combo shifter. I guess you would say its more of a shifter that you would find on a motorcycle or 4 wheeler.
Well after watching the video just now, everything I just said was basically already explained lol. Sorry for the dumbness lol.

Here is a video I posted a couple years ago. These are the hand controls that I use in my daily driver. I have this same setup in my puller. I found a used set on ebay. They would work ok but since I have to hold the brake to build boost at the line, it prohibits me from giving it throttle since my left knee is in the way.

You can't get your knee out of the way?? LOL
I can powerbrake the heck out of my truck, and my knee doesn't get in the way...
You should be able to rig up a motorcycle air shifter setup pretty easy I'd think.
Mod the handle to clear your knee. What side are you planning on putting the hand throttle on? Are you not planning on making it a spring return throttle to idle throttle?
Josh are you going to use a hob switch for lock up? btw these ross pistons have your name on them, are you ready for them?
