need help c5 with bose


got the wrong harness does anyone know wich one I need
help please thx
Which adapter (if any) was used?
Are all of the stock speakers still installed?
The ROEM-Vet1 adapter is what would normnally be used, but that may not be your problem. The dark green wire that powers up the OEM antenna and subs may just not be connected to the new radio. Check out schematic 2/4 here.
Whatever the problem is, we need more info to figure it out.
