Will a GMC wiring diagram show the car alarm?


Answer by  MarkGress (479)

It will as long as the car alarm is a factory alarm and not installed by a third party company.

If the car alarm is from the factory it may be on there. If it was installed after market it will not be on there and you will just have to run the wire yourself.

A wiring diagram will show the car alarm only if the alarm is OEM (original equipment). If it is not an OEM unit, the alarm will not be shown.
