I was playing around tonight and found unused connectors!!! There's 2 wires already wired into the doors of the 3 door astra (the most important one!) and they aren't connected and serve no purpose!!! The passenger door halfway along the bottom it's clamped down there (same on drivers) and all you have to do is find which wires match! The wires inside the thick orange sheething on the car interior side of the cabling is where it connects! I was 100% happy because i'm running mid and tweeter in the door and going active, so wanting extra wiring and it's already there!!
Well chuffed! Anyone know what it's for? the passenger side wasn't even connected to anything after a plug, the drivers side i just chopped
