Does anyone have a link to for A 99 Disco II vaccum line diagram. I'm getting 1171 and 1174 codes. I just put new Plugs, wires, Filters, and Bosch MAF. Thing is running fine but my cruise control quit working. Any help would be appreciated.

 

Do the DII's use the pump?

The DI's have a vacuum pump under a panel next to the radiator driver's side.
It's only for the cruise.

luck,greg
