reverse light switch?

[pb]

Maybe a dumb one here, but can anyone tell me where the reverse light switch is on a '75 Wagon? Both bulbs were burned out, I changed them, but still no back up lights. I'm assuming it is the switch. Thanks.

Might be the lights also. I had to run a new ground for both of them to get them to work. I dont know about a switch, I had to run mine to a separate off/on switch...
