If the blue wire you are referring to is the power antenna signal wire then yes you should be able to use it to turn on the amp if it has the remote switch contact.
Thanks guys, 2nd gens might have "blanks" in the firewall but it looks like mine has ones that are being used. The boot in the firewall on the drivers side is really tight so I didn't think I could fit a 14 gauge wire through it.
And yep I'm talking about the power antenna wire.
