No backup lights, 2002 Accord V6 coupe.

Hello,
I have a 2002 Accord V6 Coupe who's backup lights will not come on.
I have checked the bulbs and fuse and even applied power at the fuse
block to verify they work when the get power. I have tried looking for
a switch on the transmission to no avail. I even bought a new switch
from the auto parts store to see if that could help me identify the
transmisssion switch. Maybe I should be looking for a relay or
something? Its a little hard to debug when you don't have a schematic
for the circuit.
When the car is put in reverse the gear selection indicator on the
dash indicates the proper selection, but the backup lights do not
illuminate.
Any help in locating the transmission switch or other helpful hits
would be greatly appreciated.
Thank you
