86 GN Radio Question

[turbojkt]

Which one of these radios came out of an 86 GN? I sold my car and have these two radios and I don't know which one was from a GN. They have different connections on the back. One came out of an 86 GN and the other out of a 89 Olds.

Is it the one on the right or left?

Thanks

One on the left looks like my '87.

I have an 86GN and my radio is out right now. Neither look like my front because I have an equalizer on mine and the picture on the left (rear shot) looks exactly like my connections.

It's the one on the left

Everyone is right, it's the one on the left. The 21 pin configuration was used from '88 and up, you needed an adaptor for it. The one on the left, from the rear, looks just like the one in my '87 GN.
