1. Colors don't matter . . . because you cannot, and MUST NOT trust them. Even electricians code incorrectly, AND there is not a standard color code for the power wires on multi-speed (multiple winding) motors.
2. Have you checked to verify that the internal wiring on the NEW pump is actually different (apart from the switch) from the OLD pump? You'll need to download motor manuals for both, to be sure.
3. Post (or link) pictures of the motors & motor name plate PLUS pictures of the wiring terminals in both the T106 + T103R.
