Hmmm. That’s a tough one. The wiring in the harness is gone completely? Is there a different size connector for positive and negative? You could possible check what your other speakers hook up looks like and use that as a guide to which is + or -. Or maybe someone on here can check for you.

You could also temporarily hook the wires up. Push all the sound from the stereo to that corner and listen to which sounds ‘right’. If you have it reversed it’ll sound a lot more hollow without bass. Or since you’ve got it open it wouldn’t be a bad time to upgrade your speakers.
