74 challenger with ralley dash
winter project is to fix my dash light and assume the bottom hole should be for the dash light but I have no bulb or harness going to that hole. am i correct to assume that is the hole for the lamp ? I have left and right turn lights and top far right is break fail lamp i believe. Hi beam lamp goes to speedometer, thats it, also top dash i have 4 lamps in parallel, what turns these lamps on ?
