I'm upgrading my head unit (and the whole rest of the stereo as well), but I've run into a problem putting the Metra Kit back in. I can't get the heater controls plugged in, it doesn't seem to fit the factory plug. Any suggestions? Or something I may have done wrong?

 

I think I found it. I guess there are 2 plugs that look very similar, and it's been a long day.

 

I was gonna say... if it doesn't fit, you're trying to plug the wrong one in.

 

It's all in there now. Thanks for the great write-ups on this forum. They helped a lot.
