LD4B Intake question

I added triple gauges between console and ac diffuser. Mech oil psi(poly tube), elec.coolant and voltmeter). I left oem gauges in dash, just unhooked.
I may just hook up the temperature electrical gauge on my cluster. My cluster does not have an oil pressure gauge it has a light only so I installed mechanical oil and water temp gauges when the car had a 318 engine in it.
