04 ba xr6 wiring problem/won't start

[Jakus333]

Hi I recently bought a 04 xr6 ute that had a front driver's tyre blow out and somehow ripped the wiring loom out of the cabin and shredded the whole lot. So I bought a whole new wiring loom including fuse box in engine and everything lights up but engine won't kick over. Then I noticed the stereo has no power nor does the aircon or the interior lights or the windows and the original cluster gauges were stuck half way with or w/out power so I replaced that I also replaced the iss bcm and ignition all from the same vehicle and it hasn't changed anything lights are on but no1 home can any 1 please help point me in the right direction
