As always, either the power antenna or the remote turn-on for an amplifier.
It is pin G on the black plug to the radio, and it is the White wire.
Your Electronic Ignition Pack, a black box your spark plug wires come off of should have it written on the top beside each plug wire. I think the firing order is 1-6-5-4-3-2 though.
any solid core plug wire should work
Get the wire and plug it all in plug. The plug should be looking like a USB and should go in the USB.
Your amplifier should(hopefully) have an input for a "remote turn on" or some words to that effect. Hopefully your deck has either a "remote turn on" wire or a "power antenna" wire coming out the back of it. If it does, you're in business. Extend it to the "remote turn on" on the amp and you should be good!
In the trunk on the left handside there should be a wire that connects to the fuel door. pull wire that should relase fuel door.
Unless your vehicle has a built in amplifier or your installing an aftermarket one then you can leave it off. A remote wire will turn on an audio accessory if you have one.
The green wire is for ground. You can attach that to any metal part of the frame. The red is the active and coincides with the lefthand prong into the plug and the black in this case should be the Neutral and ciocides with the right prong into the plug as seen standing behind the plug.
The plug (cap) should be replaced. They can be obtained at any DIY store. Cut the old end off and prepare the wire for the new plug (cap). White wire to silver coloured screw, black wire to gold coloured screw and green wire to green coloured screw.

You only need the remote wire if you have an external amp.
Yes a remote wire is necessary. You must wire the remote wire from the amp to and ignition source of power (a component which turns on when the ignition in the car is engaged.) i.e. the radio. The remote wire signals for the amp to power on.
