Mazda B2500 location of “ unit burglar alarm “
 

Looking for location of B2500 “unit burglar alm” I’m fitting an ecu kit to my vehicle, barrel, key reader, ecu, etc I cannot find the burglar alarm unit, small black box two plugs and white and black, there was another to small boxes included in kit, small black box which was located above pedals behind fuse box and another small clear box at passenger side behind glove box, but struggling to find this other box, vehicle won’t turn over now so definitely needs it. Any help would be much appreciated thank you
