I am going to be fitting some gauges in my spare din slot. I'm going to have a gauge for Boost, Oil Pressure, Oil Temp and Voltage.
Which of these gauges will require senders? Oil Pressure and Temp only?
Where do i fit the senders, will there be a place for them already? Or wire the Voltmeter in?
Will the sender have to be a specific size?
Would there be a more useful gauge to have than the ones i have suggested?
