Ordered one and just installed it. ACM has excellent customer service.
Few install notes (that will save you time
)
If you connect the dimmer wire, you need to enable auto dim in config menu
You only need to slightly move aside the trunk/hood release panel to route the obd2 cable and tap the grey/red wire with a red T-Tap for dimmer
You need to calibrate the analog boost sensor to your altitude and conditions. The calibrate command is in the config menu, it will ask you to make sure the engine is off before it calibrates itself
