So I found that my antenna amplifier wire was cut by the previous owner and the adapter is no where to be found. So for starters I moved the amplifier to my behind my rear seat for the time being so I do not have to rip the trunk apart again. I just cut the wire and run it where my spare time should be and through the glove box space since mine is missing anyways.

Now my technical question is since I cannot find the wire that was originally plugged into the amp. Can I run the solid blue wire from the Avic unit and solder it into the hole on this amp? I see it has a prong to the outside of the male slot as well so I am a bit confused. Help me please
