Help me wire up my capri radio!!!

[stormed]

The previous owner decided to hack the dash facia to fit an aftermarket stero in my 2.0 Capri Laser. This did not come with the car, but i have recently acquired an original radio/cassette (and uncut facia) which I am am in the process of fitting.
Can anyone advise on which wires are what for the radio in my Capri Laser? I know the two pairs of brown and red wires are the LH and RH speakers, and the red wire comes from the ignition switch on the column. Then there's that white wire coming from behind the glove box, from the LH side of the dash; is this for the ariel? And obviously the big black earth lead.
Is that all there is?

Here's the back of the radio:

Does the larger spade on the bottom right corner of the radio for the red feed from the ignition?
And is the smaller spade beside marked "ariel" it for the white wire?

Here's the mess behind the dash:
