I forgot to mention that my vehicle already had the Telephone Prep SA640A, so the mounting frame and wires were already pre-installed in the trunk: I just plugged in the TCU with the wiring that was wrapped unused then repositioned the TCU MOST connectors at the MOST junction from the "unused" junction block to the "in use" junction block under the left rear seat back bolster (top of left rear wheel well). A flashlight helps identify the correct MOST cables.
