what it was, was when i bought the car the alarm, ac, heater, radio, remote locking and certain dash lights didnt work as someone had already had a go at bypassing the faulty imobiliser and other badly attempted jobs over there in the states where it came from. And as parts are so expensive to imort to uk and im on a low paid job and cant afford new parts, and most of them i dont need or want anyway i decided to remove the wiring to these items.
As said before with all the items unplugged t still ran and ive traced each empty connector back to were it joins and removed it. The only thing i couldnt find wiring diagram for was this box behind dash. Its on no alarm, ecu (pcm as its labeled), charging diagram that i have seen.
I just wanted to know if anyone does know exactly what it is then i can decide to wire it back in or leave it off.
