A previous owner disabled the neutral safety but it started great before I started work on it. I installed a new switch but can not locate any of the wires to connect to it. I have all of the wiring diagrams but they don't make sense. I followed the red with blue wire from the starter relay to the left fender then to a plug to an unknown unit attached to the back of the cruise control unit, so I'm assuming it's for the cruise control. From what I read, getting the cruise to work on these cars is a very expensive endeavor so that's not in any plans. I've already replaced the ignition switch and harness. There were red with blue wires on it which from what I see in the wiring diagram, one goes to the neutral switch and the other goes to the starter relay, but with the wire going to the cruise unit, which doesn't appear in any of the diagrams I have and nothing like them under the dash, I'm stumped and could really use some help, please.
