That looks perfect, im really only using it for oil pressure!. you mention pull up resistors i have a problem with my ECU (Emerald) wont ready my Citroen standard vehicle speed sensor on the car (i think its a hall sensor type that runs off the drive shaft in the gearbox

I know the speed sensor is fine as i have a few of them, BUT the pulse that the sensor gives off is a pulsed earth and not a 12v etc. so there are 3 wires coming from sensor + , GND, Signal

obviously ive put the + and the Ground to the battery and the signel into ECU and its not reading nothing through the ecu at all.
In the Emerald Manual it mentioned some sensor need a pull up resistor or something along lines off. its really jaring me off probably not something you can help but how do i know if a sensor need a pull up resistor?
