Check here. If the code o562 shares the Red/Brown wire in it's circuit then the connector pictured that joins those three wires could be dirty. Worth checking.

With the machine running take a voltage test off the Brown/Red wire at the solenoids and also off the shift fuse in the fuse box.
Also check the voltage at the plug pictured by me.

Update: I got a new ECU (note the one from Partzilla which is backordered) but a used one from a 2015 viper. I got it all back together last night and she's running like a dream. So turns I did fry the ECU by boosting it....
