So to add to this I been troubleshooting my gauges.
Speedometer needs 12v and a signal coming from the speed sensor to work. Fuel gauge draws its power from the speedometer by piggy backing from the speedometer, and the fuel gauge reads from the baffle ohms measurements. An open would suggest a short in the baffle fuse. To check use a ohms meter n test the baffle plug, and to check if the fuel gauge works short the cable where the baffle would plug into, it should cause the gauge to read as full
