Hi Today I bought an alarm for my car, but when checking the box it does not bring an installation manual, will someone have a manual of this alarm? or some guide that serves me, since I connect some things and it does not turn on the led light that it brings, the one that indicates that it is working, also does not bring to connect the "connector" of centralized closure, will it bring it included in any connector? . The alarm is Beste brand model G4.
