you have not made mention of the steering angle sensor input , to the power steering computer / controller / black box

on VW Audi this is a critical input delivered by the network to the steering rack which has the PS pump built in

key work here is
network -
no doubt the partial toyota network that may exist in the p/s unit does not communicate with the dodge network .

it may function anyway as the VW PS systems will function even if the system codeing is set incorrectly so that the system looks for the steering angle sensor in the wrong location -
but - those systems set DTCs - every where

the WOT cutout can be sampled at the AC compressor as it has a WOT cutout as well , the TPS is not a good choice for this input .
