Mach Head Unit install issue-HELP!

[Westbayou]

I purchased a Mach 460 6-disc head unit out of a 2004 Mach 1 and just tried to install it in my 2004 Cobra Vert. The smaller of the 2 plugs, the gray one, does not match up with the small plug on the back of the Mach unit I purchased. Any suggestions or ideas??? Guess I'll put the Alpine back in for now?

I think that is a 03 Mach head unit. I think the 04 has a cd/aux button on the top left instead of the shuf button that you have.

Yeah, that is what I thought, just wanted to make sure. I should have asked for pictures first I guess. Oh well, I'll figure something out.

The 04 should look like this on the back

Yup, those would be the plugs I needed.
