07 chevy suburban speed sense

i'm working on a 07 chevy suburban doing a pioneer z1 and i need the speed sense wire for this car. it has the full package with onstar. also does anyone know how i can bypass the z1 for viewing the dvd where driving? thank you.ohNelly!

     Speed Sense          D. GREEN / WHITE          (AC)          AT RADIO C4 ORANGE CONN PIN 5

cant find the wire. tried at the radio, tried under the hood, under the dash all over none of the d. GREEN / WHITE works. also someone told me that it was BLACK / YELLOW under the hood but still noohNelly!

I haven't worked on one of the new GM suv's .... buuuuuuut .... in the past, when I could not find the specified VSS wire, I've used the wiring from one of the front wheels' ABS sensors. I've done this plenty of times. It did not work twice - on an OLD Mercedes and a Caravan of some type. I forget the vehilce specifics for the no-go's. All others have worked fine, including many many H2's (similar?)

Try looking for a 24 pin plug under the hood above the driver's wheel well. The dark GREEN / WHITE will be in cavity B6. It may not be at the radio unless you have a factory Nav radio.sparky

i found it! it was under the hood, behind the driver's headlight. it was yellow/black at the ECM. thanks everybody.ohNelly!
