99 z28 bcm issues
 

I did the window/radio bcm fix, reinstalled, heard a clicking fr bcm every6-8 seconds, clicking stopped, now reverse lights and dash lights dont work, did i go too hot? Fuses are fine, i have a used one fr a 01v6 auto, mine is a 99z28 m6 and has what looks like a wire handle to remove circuit board, used one does not, i see a whole lot of used ones on ebay so there must be something i can do. What is the process if i buy the 14 resistors that cost like 3.99 on ebay? I read somewhere that i can reprogram ussd bcm to my key by turning on and off and this and that, takes 30 min, is this correct?
