Hi Victor, My name is***** will be glad to help. It is unfortunate that someone hacked the wiring and in this case it could have been any circuit that fried but then melted and shorted with another circuit. Test all your fuses on both sides for power and check your relays as well by swapping with a known good one. This will help isolate what circuits are shorted if the fuses blew. It is possible the PCM was damaged from the short but check the harness and connector pins thoroughly first for any harness repairs/replacement that is needed. Let me know
