Hey guys. Running into a weird situation. I'm working on an 89LX (checked the vin etc as well) and he wants to put the OEM radio back in. It has what looks like the premium sound with the 6 speakers. However the OEM amp was missing. There are 2 plugs that I believe should go to the amp right behind the radio. However the weird thing is one is gray, and one is green. Both have round pins. Where as every amp I find for those years have the 2 gray plugs with square pins... I found one on E-bay with what looked to be the correct plugs, but when it showed up it ended up being the gray and gray plugs anyway. So I stole the pic from there and i'm hoping to figure out whats going on here. Any ideas?
