2007 R1200RT - Looking for built-in second horn lead

[pauljohnson12]

Can anyone point me to the (supposed) second horn lead in the harness of my 2007 R1200RT? I would assume it’s in the same general area as the existing horn lead? I’ve done some looking, but it seems that the harness is bundled pretty tightly, and I don’t want to randomly start cutting zip ties and harness wrap. Any suggestions?
Thanks in advance,
A new owner.

Your assumption is reasonable, as shown by these pictures from the MAX parts website -

However, they also show a single horn setup, with a different bracket.
I don't have a schematic for that bike, but in the past, horn wire colors are brown for ground (of course), and either green with a blue runner or green with a gray runner for the switched +12 volts.
If there is an additional plug for a 2nd horn, it would probably be gray on the outside and either blue or blue and white inside. Or do they use a simple jumper between the two...?

My schematic CD show the 2007 RT has 2 X 2pin horn connectors.

Horn#1 H9151 Green/Grey (from pin 43 from ZFE) & Brown (-)
Horn#2 H9152 Green/Black (from pin 56 from ZFE) & Brown (-)

The second horn mounts behind the left side fairing panel (with roundel) and the connector is there.

The horns fwiw are BMW 5-series car items.
