Rx8 reverse lights not working

I had my transmission replaced some months ago. Now, the backup lights are not working. Just noticed it. Bulbs are good. Can't determine which fuse is correct. Don't know where to find/connect the tranny switch or it this is a computer issue.

This is a 2005 6Spd Manual RX8. Series I

Anyone deal with this before? Need to get the reverse lights working for inspection.
