Flickering back lights

Thank you very much, it was the ground connection. Wish I came here to 2CarPros before seeing a certified electrical car specialist from a certain busy. Having us replace the multi-function signal switch. Which didn't solve the problem.

Also after having the the multi-function turn signal replaced. We got a engine light code for the Knock sensors. And now the door locks doesn't lock with the remote and the drive side is the only one that doesn't have to he down individually. And the cargo door ajar light went off when the ground connection was fixed Just had all O2 sensors replaced and brand new battery.

Problems still exist and now without warning the check engine oil pressure light came on while driving and new sounds came from the truck. Knocking/clunking noises. Took it to the shop next day, without really checking the truck, suggested oil change with a higher oil due to mileage 304, 907. Sent us to autozone in the truck, returned oil change done, light still on, noise still there, said give it 2 days if light still on bring back and change the oil switch. Got down the street and first time every truck shuts off. Had auto zone run codes, PO305, already replaced wires, ignition coils and spark plugs. PO157, replaced all up/down weeks before. PO327 was scheduled to be replaced this weekend. Back to shop, owner said without checking truck, need new motor. Never shut off before until they changed the oil and used 10W 30 with Lucas stabilizer. Oh also, was told that the knocking sound was do to my husband putting regular Unleaded, and regularly uses premium unleaded. We at a lost. No leaks anywhere. Never was told about sending unit could be bad or the oil pump.

Sorry it took so long. Here's the video. Had it checked by a mobile mechanic yesterday. First said need a sending unit. Oil switch. From the quote given online. Got here inspected the truck said I need a motor. Metal shavings in the oil. I'm looking for a used motor or a rebuilt motor kit.
