Discovery II Cruise Control

Hi guys,

My cruise control is not working. I've checked the switch it is fine and the vacuum cable seems good. However, is there anything attached to this two inlets maybe a cap or a cable. The two inlets one is white or maybe yellowish and another is black.

Help appreciated.

Thanks

:doh:

Just looked at mine to see whats what as mine stopped working on the way home and it would appear the hose from the pump goes from the black one (in your picture) to the controller for the cruise to work.

Nick.
