dude it is so easy. i do all my own wiring to my ride. well i do all my own installs period. added a 3" lift, 6 roof lights, 4 bumper driving lights, underglow, wheel well glow, subs, new head unit.
but anyways, to take the dash off it takes 5 mins if that. just get the appropriate size allen tool. and unscrew the 16 screws. just pull the dash off from the corners, get the tricky one under the radio, just pull it straight off. and walla its off. make sure lower steering wheel, makes it easier. and then just unscrew the 4 screws holding radio on.
