I,ve been retro fitting the 13 button OBC today.
I,m left with 2 connectors at the glovebox end, one is a 2 Pin White Connector with a Blue and a Brown cable,this i think connects to the white connection block above the glovebox.It looks like there is a space available.
The other is a 4 Pin Green Connector which has GRN/RD,GRN,BRN and a BRN/YL cables.
There appears to be one Green Female Connector available,but it is already occupied.
Can anybody give me some advice,or even better a photograph?
I,ve looked at E30Adam,s Wiki on the subject and Bentley and Hayes are not much help.

Thanks for the replies.
Alex,yes i have the 'restoration bible'.
It looks like the white connector with blue/brown connections is for the temp sensor.
That still leaves me with the 4 pin green connector grn/rd,grn,brn,and brn/yl wires.
Not sure what thats for.

Green/red and green are the immobiliser loop, the brown is an earth, and the brown/yellow is the alarm horn. You are missing the front section of the loom, which has another plug for the green and green/red.

I never connected the immobiliser part of my OBC as it is pretty pointless. Will work fine without it
