[Its a super Pro AVi don't know if the other models have different size boxes]
Live feed picked-up from the horn fuse.
I think there's some advice on what live feed you use depending on the model of your 1150, IIRC, taking it from the tail lamp is not advised on Servo-ABS models because the circuit is used as part of the system test on start-up).
Mine's the same, and I keep it in the under-seat tool tray, having removed a few of the crappy tools.
