any ideas? im thinking it should be on the factory harness because the stock radio would get louder as you go faster but i dont know which wire it is!

Speed Sense brown (3.5L only) PCM, blue plug, pin 22

That's only if you have the 3.5L, PCM is in front of the battery, you MIGHT have a brown wire on your factory radio harness which will be the speed sense but I would put a fuse on it to be sure.

The power interface module is behind the driver's kick panel, find a brown wire there.

is there a chance you can post pictures of this wire, i have a 06 GT g6, and i've been looking for this wire, along with the illumination wire. no one seems to haave found it.

Any help would be appreciated.

No photos, sorry. But the power interface module is behind the driver's kick panel, VSS is brown. Illumination is activated through the LAN serial data line running throughout the vehicle, along with accessory.

In normal people terms, that means you'll have to run a wire from the bcm to the radio opening. Here's where you can pick up the parking light feed.

Parking Lights+ brown + BCM, C3, pin A7
Notes: The BCM (Body Control Module) is part of the fuse/relay box on the front passenger side of the center console. It has the following connectors: C1-72 pin gray plug, C2-72 pin gray plug, C3-41 pin red plug, and C4-68 pin lt. gray plug.
