CHP PNL - CRS2 does not control CRS 2!
Both CRS knobs control CRS1 only.

Lvars in manual:
Course Knob CCW H:CHP_CourseKnob_Left_1
Course Knob CW H:CHP_CourseKnob_Right_1
Course Knob Push H:CHP_CourseKnobPush_1

Nothing for CRS2!
However, using external hardware I can use VOR OBI1 & VOR OBI2.

From ~page 63 of the manual:

The two course (CRS) knobs are used to adjust the active and preset navigation courses. One might expect the CRS1 CHP knob to adjust the active navigation source and the CRS2 knob to adjust the preset course; however, they actually control the pilot and copilot’s active navigation source unless the associated CDU is displaying the Preset Nav Source screen.

The FAQ provides some more information:

Counterintuitively, the CRS2 knob does not always control the preset NAV course. Instead, the CRS1 knob controls the pilot’s side active NAV course, and the CRS2 knob controls the copilot’s side active NAV course. Both knobs will only control their respective side’s preset NAV course when the on-side CDU is displaying the Preset NAV Source screen.

Always let me know if you have any questions!
