Left handed ebike thumb throttle?

I have a TidalForce M-750 (the bike with 36v NiMH battery pack in the front hub and 1kw motor in the rear hub) and post-polio syndrome in my right arm. I'd like to move the thumb throttle to the left-hand side of the handlebars for easier use and to clear the clutter on the right-hand side. Just shifting the CCW rotating shifter to the left results in a very awkward result as you can guess! https://www.bikeforums.net/images/smilies/brood.gif Right-handed rotary grip throttles won't work since the SRAM shifter is a grip shifter, and replacing it with a SRAM trigger shifter still takes up a LOT of right-hand side handlebar space with the controller and brake lever.

Anyway, here's the scoop. I THINK the throttle is a 5k ohm rotary potentiometer with 3 wires - +V, ground, +V(wiper). I've found a left-handed thumb throttle at URL https://www.poweridestore.com but the phone # is disconnected, the cell phone # message machine is full, and the order store says no longer in stock.

Any ideas?
Thanks

i've been pondering the same thing.
as i had planned to have 2 e-wheel installed.

front + back, so i needed some sort of throttle to control the front wheel, as the rear wheel is already set for assistance.

Thumb throttle update

The right hand thumb throttle that is on the Tidalforce ebikes appears to be an AWI 0 to 5k ohm rotary potentiometer throttle. Found good picture and put a meter on the throttle. Red wire is +V, black wire is ground or -V, and the brown wire is the rotary pot wiper wire. Still looking for a left hand side thumb throttle.
