1963 Valiant V200 Wagon

well i spent today finishing up my headlights. they work fine, but my tail lights dont seem to be working. just my brake lights. also none of my dash lights are working. i have a new healight switch so i dont think that could be it. my gas gauge worked once, but only once. and the high beam indicator works if you push on the bulb socket. considering im not even using the ammeter or factory temp gauge, i have been thinking of just making a custom gauge cluster with new working gauges and lights. what do you guys think. i liked the idea of keeping the stock cluster, but its not worth it to me to have it restored for a speedometer and fuel gauge. tomorrow i am going to check everything with my multimeter and make sure the headlight switch is working correctly.
