Two more things of note:
You can find the Toyota FSM for the 2000 MR2 here ->

For the Dodge, be sure to either reconnect the stock power steering pressure switch to its electrical connector, or jumper the two connector terminals together. Otherwise, the Dodge engine computer thinks the power steering is under load, and will throw a P0551 code with a CEL when you drive above 40 MPH.
