no daytime running lights or tailights

hey guys i was attempting to fix my buddies regal he has no inside lights at all and sometimes a very dim radio mostly just nothing...so i went to look at his dimmer/headlight switch and i seen one part was burned on the male end and on the female end the harness was cracked...long story short i was checking the power supplies and i think i jumped a wire together cause i heard a click and his radio lights are bright as ever but no cluster lights still....and NOW he has NO daytime running lights what so ever...and he has no taillights now either just brake lights....i check every single fuse on that car there all good. anyone know what the hell i did to this mans car lol? ...i just bought a new headlight switch thinking that was it because auto zone agreed i put it in and still nothing...they wont let me bring it back of course lol and then suggested its the body control module...and i think a dealer has to put them in..anyone have any suggestions?

Regals have been around a long time- I drove my Dad's in high school 1977- so what year is your buddy's?

The radio light is bright now because the park lamp feed input is off- due to the tail lamp (park lamp) circuit is now dead.

Once you provide the year, we can look at the wiring diagram and advise you with test point ideas.
