Aside from normal power & speaker wiring, do the following connections appear correct: -Speed Sensor (grn/wht to vehicle speed signal (Dk grn/white at I/P relay block) - Parking Brake (yellow/blue)- does not appear to be vehicle parking brake signal -For an Idatalink Maestro steering wheel control interface does SWI-1 (PURPLE / red, connector A1, pin 1) connect to vehicle remote radio control signal (lt grn, A7 @ BCM, C3 connector), or to vehicle datalink connection to radio (orange A1,C1, lt grey connector)?

Sounds about right but I never worked with the Maestro interfaces. You shouldn't really need that speed sense wire sir. You may only notice a slight difference in how well the system can track and triangulate with or without it.there can be only one.......

The only time it uses the speed sense is if it loses signal from the satellites, such as in a parking garage or a tunnel.

That is true but the VSS should be easily accessible behind the instrument cluster. GREEN / WHITE. Pretty sure it is the only GREEN / WHITE back there. That is for 03-07 silveradosTo master and control electricity is perfection. *evil laugh*

if you want to get into the advanced menus and watch videos you will need parking brake and foot brake hooked up. you can also use a timed relay to do the sequence on them.
