E150 van cruise control

Just bought an E150 van with a cruise contol that won;t turn on, bought Childen's manual but has very little on the cruise control. Does anyone know where I can find a wiring schematic, the ohms it uses so I can check with my meter, or any other info on things to check and how to do it?

Try a Haynes manual. Haynes includes some diagrams. If you have a friendly local Ford dealer that has a shop manual for the year van you have, they may let you copy diagrams out of it. Manuals and diagrams are also available to dealers online. Again, If you find the right dealer, they may download them if your year van is available.
