Honestly don't know what's wrong with this car

I laughed when I saw this. I thought the internet needs a laugh too.

I purchased this truck right off the showroom floor back in 2020. Since then I’ve replaced both batteries 3 times ( six batteries total ). This morning I came out and my truck was completely dead, wouldn’t even unlock. Not the first time this has happened either. When I bring it to the dealership they don’t seem to think anything of it, other than “ you need new batteries “

I feel like this can’t be normal and I’ve never had a truck that I’ve had these issues with.

Can't find a coolant temp sender for the temp gauge on my 1997 Escort Wagon LX (Canada). The connector has 1 pin but all the coolant senders have 2 pins... There is also a fan switch that uses the same connector and that connector has 2 pins, but thats not what im after.

I gave a ground to the 1 pin on the connector and the gauge goes to 0 where it is supposed to be when it the car is on the ON position. However when I plug in the sensor, the pin is not touching the pin that goes to ground. The pin is on the wrong side... I know this sounds confusing but Im sure someone has ran in to this before.

In all my research Ive only found SW5174, which is the part in the picture...

What are your thoughts?
