hey all, new to the forum and have a quick beg...? anyone by chance have a wiring diagram handy for 03 mustang v6 under dash fuse box? i mean the actual harness diagram. seems i only have 12 volts on one side of f.21 and i'd like to try and see which wire it is and where it goes, maybe i have been in area making quick places to start. isn't it always hot for pcm if i am not mistaken? many thanks in advance
