Cadillac Repair: cruise control does not engage., cruise control, light switch

Question
cruise control in my 1987 cadillac refuses to engage. The cruise control light switch lights up and the letters tell me on the dash that cruise control is on, but the cruise control does not engage.  I found a wire under the dash disconnected, but i wanted to ask you before i connect this grey colored wire.  the shape of the connector end is dome shaped and a receiver dome shaped is also there disconnected, except that one wire is grey comming from the steering area and the other end is a different color, eventhough boyh ends seem to be dome shaped.  Please help. joe.

Answer
Hello,


I haven't worked on one of these for 15 yrars. The only thing I can tell you is send me a pic of both connectors and it might jar my memory. Send to robo14@aol.com

I worked on these cruise systems to a point, but I don't consider myself fully knowledgable on diagnostics.

There is a lot more to it than you see. The cruise is controlled by tge ecm (computer) as well.
