is it possible to hook up the 07 ss head unit to the current wires of the 06 would it be plug and play thanks just like that new look better

 

I jus swapped a aftermarket into my wifes 07 and the plugs are not the same. The harness is way different and was a pain in the ass to find the new harness for the 07. My 06 was easy an the HHR harness is the same.
