Tricky Question, Expert advice needed!

[RowanVW 0]

I have recently bought a 1.8 16v, taken it off carbs and back onto standard air box and fuelling:

 

Can anyone make sense of this wiring, when i turn the car to start it the relays start clicking like crazy and a buzzer/ beeping starts! The first photo shows the plug disconnected from the back of the ignition barrel where some amateur splicing has been done!

 

 

 

When i click the black switch with the two red spade connectors on it down, (from the first picture) it activates the MFA on the dials, I can only assume the previous owner has tried to bypass the immobiliser as that was in the car, but not connected to anything and there was no passkey with it.

 

The small red button appears to do nothing at all

 

Any advice anyone can give would be greatly appreciated as i'm fairly novice at wiring! Help get me driving my lovely car for summer!

 

Thanks, Rowan

Ah, the joys of aftermarket alarm and immobiliser fitment! Only thing to do is strip out anything that's not OEM and solder in new sections of cable, all the VW stuff should be clearly and uniquely colour coded, so it should be just a big jigsaw puzzle, don't envy your job though :(
