Hi, I got my hand on a OEM amp. PN: 15268846 Also has this number GM-2257ZG. I could not find any links for the GM-2257ZG number on the web.

This amp has 3 connectors, 1 has 8 pins and the other 2 have 16 pins each.
When I look at the sticky, there are only references to 1 8 pin connector and 1 24 pin connector.
If I put the part number on ACDelco.com, I get this description AMPLIFIER,RDO SPKR
ACDelco lists all flavors of the Cobalt as being compatible (LS, LT, LTZ, SS, SS/SC)

Would any one have the pin out for this amp?

Help is very appreciated.

THanks
