Gary: Are you trying to solve your problem or Manny's (the OP)?
Be easier to do these one at a time - even seperate threads would be good.
Its almost a given one of Manny's headlight wires is contacting the start wire to the relay, especially if it only happens when the headlight switch causes the starter to turn when the headlights are on. If it happens when parking lights are on, then its a wire in that circuit (or instrument illumination).
Do yourself a favor and download the Dodge Service manual for your year. Then you'll have the best reference for colors etc. It still may have mistakes but less than the non-factory diagrams like those on mymopar.
For your problems with the signal and marker lamps take a look at the guidance from Tech. Using the FSM wiring diagrams, make a schematic - it may be the same as one of those shown in the Master Tech booklets, but it may be a little different.
