Lectric xPeak 2.0 Twist Throttle

[haneyrm]

I just received my xPeak 2.0 and would like to change the thumb throttle to a twist throttle. I have a twist throttle with a 3 pin orange plug which has worked fine on my other bikes (Velotric and Ride1Up) but I just get an error on the xPeak.

Any thoughts on why this works on these other bikes but not on the xPeak? Recommendations for one that will work?

Thanks in advance.
