99 Suburban brake/reverse light issue

Got a problem with my reverse lights coming on when i hit the brakes. Also, both left and right brake lights come on when i signal to turn rt (along with white reverse lights). Left turn works fine. All bulbs are clear, no discoloration, and both rear light units were completely replace a few years ago. Any ideas for fix?

Is your '99 Sub an Old Body Style (Looks like a '95) or New Body Style (Looks like an '02)?

Sorry, i should have been more specific. 99' Chevy suburban, LT, 5.7 V8, 1500. Body style is "old".

with the problems you mention this is IMO a bad wiring repair job. IF with a trailer hook up wiring I can believe this is happening. not a OEM manufacturer type of failure. someone messed with the wiring.

thanks icat. will check it out.
