When adding an aftermarket alarm system, will the harness have to be spliced into?
Planning an audio build in the near future and don't want that to mess with me. Just recently added a new HU and the harness I had to buy was a pain to fit in he space I had...
Just not sure where alarm stuff goes, so I came to ask you guys.

The radio harness will not have to be spliced into. Other wires in the car, of course. The alarm needs the status of specific factory wires (door pins, lock/unlock, etc) and needs +12V constant and ignition power sources.
