I recall when I installed a water temperature gauge in my I/S...
I bought Autometer because they are reliable and made in the good and oldie USA. They had the model I wanted in 2 options: *with* the wiring harness (20 bucks or something) or *without* it.
I choose the one *without* the harness trying to save 20 bucks... Damn, it is not rocket science! Just 3 wires (power, ground, sensor). Right?
Then I had to buy 3 colors of wire (black, red, green), connectors, solder and shrink wrap tubing... ended up spending over 50 bucks.
