2002 stock vw tape deck into mk1... need s-contact/alarm feed

[CaddyStack]

So I'm trying to put a stock tape deck from an 02 golf in my 82 Caddy and can get the red led blinking and load/ eject tapes, but it won't actually power up... I assume the s contact and/ or alarm wires want some juice, but 12v doesn't do the trick. Here's the link to the radio diagram I'm working with. I know this is an odd choice, but I have my reasons...
Thanks in advance!

S would be power when key is in the ignition to keep the radio live

alarm as I recall is just a "pass thru" for the alarm circuit (think Christmas lights, when one burns out, or in this case disabled it would trigger the alarm)

does this need a code? if it does, you need it. the radio should power on with + and - hooked to it. if not, it's dead most likely

display should light up and say CODE or have 00000 across the screen...possibly SAFE, can't recall.

Awesome... so from the diagrams I've looked at the alarm does look like a pass thru. I am guessing that it shouldn't need any connection then, eh?
