2007 chevy tahoe speaker wiring

Wanting to see if anyone has had any experience with the 2007 tahoes.  They have only been on the market for a little over a month and GM has no oem part numbers for anything.  I will be installing a pioneer N-2 and eally just need to see if anyone knows what color the speakers are for the front rear and subwoofer.  Thanks

I see no reason for GM to change colors, so it should be the same colors they've used for years: lf tan(+)/grey(-), rf light green(+)/dark green(-), lr brown(+) / YELLOW(-), rr dark blue(+)/light blue(-).  I don't remember the sub wire colors, but it'll be obvious when you see them- I believe the negatives have a black stripe.  They do have standard speaker terminals- big one is positive, little one negative.
