What part of the Colorado wiring diagram do you need?What are you doing?
im trying to install a new stereo. need to know which ones link up
Please understand that the Factory Radio is a Class 2 DATA Type Radio & it is also used for different components in the vehicleYou should use a Radio /DATA Adapter (Wal-Mart, etc.) that has wire for wire & color for color fool proof wiring install. Like the Scosche GM09SRThe Wiring Adapter also gives you a Ignition / Accessory Output that is NOT on the Factory Radio wiresYou will also need a Antenna Adapter
Here is Factory Speaker wires
Left Front Speaker(+) TAN Left Front Speaker(-) GREY Right Front Speaker(+) LT GREEN Right Front Speaker(-) DK GREEN Left Rear Speaker(+) BROWN Left Rear Speaker(-) YELLOW Right Rear Speaker(+) BROWN Right Rear Speaker(-) YELLOW
Please keep in mind Just Answer is set up on an honor system.
I have sent the information you have requested.
If there is a problem, let me know, as hard wiring should not be done
