Need Gauge help. Thanks

Thanks for help.
Disconnected temp gauge wire and everything is back to how she was.No smells, Ammeter and all indicator lights work fine and no temp or fuel gauges. Started Tracing temp gauge wire and was cracked with exposed wire and barely hanging together were it bends and shoots into harness with alternator wiring.
Hopefully that will fix temporarily until I replace bulkhead forward harness since everything is so brittle.
