Currently Adding an Amp to 2005 X5 with Nav, no DSP and no OEM amp
I have located the 16pin Tuner plug/wires on the tuner module under the tyre. I need would like to connect remote turn-on for the Amp.

I have searched the forum but there only seem to be references to people with OEM amp plugs which is not in my car (UK specs) so I guess I have to take my connections from the Tuner Module

ok I have located two wires per articles on the forum:-
pin 13 :- White
pin 16 :- white/purple
cable on pin 16 is thicker.

I tested both wires for current using one of those tester screwdrivers with a bulb and both wires come on with ignition keys in position I regardless of the monitor beign on/off

which of these two should i connect the remote amp turn-on to?

cheers
