Alternative Temperature Sending Unit Install
I'm looking for a point to install a SPAL temp sending unit. I have an 04 5.4 engine. On the driver side of the engine, lower area closer to the rear, next to the heater block tap, there is a small plug. Looking for opinions if i can use that for the sending unit and if anyone knows the size and thread of the tap. Thanks!
