I need some help please.. I have a 1970 , 340 Duster with a rallye dash. About two years ago I took the dash out to paint the car. I recently reinstalled the dash ( instrument cluster ) but I'm having some issues.. Like gas gauge, temp gauge, and tach not working.. Does anyone have any pics of what wires goe where on the back of the cluster ? Or can someone just tell me what goes where ? Does the tach wire hook to the - negative side of the coil ??? Thanks..
