ETACS, immobilizer

Greetings, my name is Luis Buchelli C, I am from Ecuador I have a Terracan 2.9 4WD 2006, I had a problem with the ETACs, which is the electronic immobilizer that cuts the food of the injectors, the anti -strap lighthouses, windows, doors.
My question is that the part number is:
95400H1501, but only found 95400H1401, someone can tell me the difference. It can be installed in the vehicle

thanks
