i am looking at the schematic for the cruise control system and i see that the speed signal is picked up electrically off the back of the speedo cluster. without pulling my speedo off to check, does anyone know if this is a milliamp signal, or a 12 volt pulse that triggers the cruise control box.
( i have a friend with an 85 vmaxx and he has an 86 venture that he wants to pull the cruise off and put on the vmaxx.)
