I just did this on my project. This sequence worked for me.
1. Fit the switch panel bezel into the dash on the left and attach the wiring connectors. Leave it loose.
2. Blue tape the right edge.
3. Attach gauge cluster wiring and install cluster to dash frame.
4. Blue tape the gauge bezel left edge.
5. Gently fit gauge bezel into the right side. Then, the gently work it into postion behind the switch bezel and install.
6. Install the switch bezel.
See the results here.
