Just fitted an Alpine iDA X100 HU to my GSi.
Can I hook up the orange dimmer wire to the car, and if so, where would it go?
That display is BRIGHT!
(Although, being an engineer I haven't read the instructions yet so don't know if I can do it on the HU itself! )
Hook it up to the grey/yellow on the iso block, this is the dimmer wire on the car
