we changed the dash for the idiot lights and still does not show turn signal indicators or headlights on dash. This is on a 1990 jeep with a 302 ford v8. where does the dash get its power to these indicators? The pugs are plugged in good and clean. We just put a like new dash piece in it. Would like to have an idea where to look. Dont want to take it all apart again. All out side lights work and so does the turn signals.
