Trying to fix the fuel gauge on my Datsun 240z - Not sure it worked

My attempt to try to fix the fuel gauge on my Datsun 240z by reconnecting the leads from the fuel sending unit. I think that maybe it worked, but I need to drive the car for a bit to make sure the gauge is functioning correctly. I also talk about the switches that are installed in the dash. Link to my video on installing the battery disconnect switch:    • 12 volt Battery Shut Off (Disconnect) Swit...   Link to the fuel sending connection wires from zCarDepot https://zcardepot.com/catalog/product...
