Easiest way to get the terminal you need is from a Metra 71-1761 or Scosche TA02RB harness. The HU is providing a 12V output on that pin. You need to add that pin/wire to your car's 10-pin plug, then connect the free end to the wire on your car's AM/FM antenna plug. That will send the 12V from the HU out to your booster amplifier.
As a temporary fix/test, you can connect a small-gauge wire from pin #3 on the 10-pin (+12V Accessory power from the car) over to the wire on the AM/FM antenna plug.
But before you do either of those, you need to verify that the HU is not already supplying 12V to that wire on the antenna plug.

Pin #8 is def feeding out 12V (power leaving the radio itself), but now that I pay attention it is a bit weak radio reception. Would connecting that pun to something help me?
