Apologies if this has been raised before, but I have been strggling to find an answer.

I can see that one of the ports on the green plug (the one that is plugged into the back of the clocks) is for the cruise control..but what of the rest?

What function do the rest of these ports perform ?..

Any input would be weelcome.

Cheers

All of them output the same signal - they're just available slots if you have other speed-dependent accessories, such as (I think) the obc, cruise control or the stereo's volume.

Thanks Grrr....im actually retrofitting an OBC (13 button) and was of the view that the speed ect was taken from the loom with the yellow plug?

Is their a seperate loom from the green plug for the OBC?..am now confused.

I put "i think" because I can't remember specifically. If you're unsure, check the OBC retrofit guide:

All signals for the OBC, except external temp. are via the yellow socket.
