Aftermarket amp / power antenna wiring question Options

[pandito]

So I've spent a good portion of last night and this morning trying to find an answer but have so far only found frustration. I've gone through so many posts and I still can't find the droids I'm looking for.

I am "upgrading" my stereo from an older Pioneer model to a newer one. I will be reusing the Metra 70-8112 Amp Integration Harness and wiring it into the newer Pioneer's wiring harness but am getting no sound. Nor is my power antenna coming up.

For information: I had to order a wiring harness from Xtenzi (H/U was from a friend and I've seen it work). Here's the Metra amp integration harness that I am using (though I'm sure y'all already know (of) it).

When I clipped the old Pioneer's wiring harness, the blue (power antenna) wire was mated with the blue-white (AMP turn on) wire on the Pioneer end and those two were connected to the blue-white wire on the Metra.

I remember reading that there's a unique circular issue where the amps don't turn on if the stereo doesn't get a signal and therefore the speakers don't work with the amps not on.

Anyhow, I mimicked how the old harness was wired (mated the blue and the blue-white on the Metra and connected them to the blue-white on the new Pioneer Harness - pic. No sound.

I feared I blew an amp so I went ahead and plugged in my OEM radio and it worked perfectly fine. Am I missing something?? Any input would be really helpful.
