2017 express l6 won't go after jacking with reverse beeper switch

[gtex1970]

i went to unplug the reverse beeper and plug in some led lights I have mounted out back. the beeper is quite annoying and reverse lights would almost serve the same purpose (in my mind). i must have shorted something, it won't go now. I put everything back as it was, but there's no 12v at the reverse switch now. all fuses on the panel near the battery are good. is there another fuse panel somewhere?

any help appreciated,
greg
