Car audio not working?

hi all,

i'm poor, 92 ford escort broke down , bought 94 chevy cavalier didn't come stereo, looks of radio stolen because wires cut. took factory stereo escort , tried putting in cavalier using wiring schematics listed below. there 2 yellow wires i'm not sure which, tried both , neither worked. nothing in stereo turns on, thought @ first theft protection of sort, doesn't have turn on set code? i've checked fuses , although there isn't separate 1 radio, doesn't blown, , made sure take neg. off battery.
