Radio and power locks aren't working after testing a plug for power

Radio and power locks aren't working after testing a plug for power Tested a plug to see if it was hot cause I couldnt find where it went to. And I accidentally crossed power, the radio quit and the power locks dont work. I went through fuses n dont see any bad one. The radio is not factory so I checked the fuse on it also. All good. Is there another safety fuse hidden somewhere? Also the lid on box doesn't have power lock fuse locator?
