Green wire explained by Tore in the same thread:

ToreB said:
Green wire is the alarm wire. It has been connected to the original head unit frame, and was grounded when the unit was extracted. Insulate with tape/shrink tube and tuck away.

Cheers,
Tore
 
The green wire should be earthed to the body of the radio, and the body earthed.

Get a circuit tester from Halfords
 
The green wire must be insulated and tucked away. Connecting it to GND will trip the alarm. This is also what happens when the origninal radio was pulled out of the frame. The green wire was connected to a switch on the frame.
Cheers,
Tore
 
Brill, Thanks for responses guys v helpful.
Had this Becker since Jan having bought it on eBay but not realiising it came with no leads. It's taken me an age to source the connectors via USA and now seems the damn thing doesn't work anyway!
And I've spent so long getting this far I have no redress with seller
But at least I know how to wire up the next one!
 
Have you considered getting it repaired? Can recommend CARS in Bolton area. They fixed a mid 90s Becker for me recently.
 
Hi Harry,

Once I've confirmed its faulty I will try and get repaired so thanks for the lead.

I have also found a Putnoe Radio Services (apparently uk repairer for Becker) but previously left them a phone message and they never got back to me
