I can not find a schematic for the 1970 396SS turbo 400 Kickdown harness. There are two wires that are suppose to come from the transmission switch located on the drivers side of the tranny. These wires are Orange and the other is Black. I am pretty sure I see where the orange one goes as I have a cut wire pertruding out of my fire wall (aside of an ignition wire,black with purple line) But I don't know where does the Solid black wire go from the actual switch on the tranny. Please help...
