Idiot light questions from a dummy

I agree, u can get Mopar sending units for the lights that will screw right into those ports. Sending units for a gauge are different so make sure u get the right ones. Kim
Sounds good Kim. I just wasn’t sure, especially on the oil ports on the back of the block. There are two ports opposite each other and one is currently just plugged. Could it be as easy as just threading a sending unit into one side and leaving the pressure line hooked up to the other?
