deano,
yes that is what I will be doing on the BLUE wire (radio mute).
Here is a Hong Kong vendor with nice chart at the bottom of the ad explaining all the connections.
I like this one better because it has screw terminals for the wires too.

Tman has found the china version 1/2 the price of the Hong Kong version, maybe the Hong Kong ships faster...
