navigation voice command switch

[BOBD]

I have a 2006 SE and purchased a navigation unit E7009 from OEMVALUE.com and installed it.I also purchased the JDM voice command microphone kit from Carson Toyota.OEM web site has hook up instructions for the microphone but not for the push button switch.One wire from the switch is connected to the microphone negative and shield wire.I need to know what pin on the R10 connector the other switch wire connects to.I appreciate any help anyone can give me on this.
