Transmission temp gauge

Hey i have an aftermarket cd radio in my car and i have the old cd player in the bottom slot still. I wired up a 3 toggle switch panel that i want to mount in the place of the old cd player and next to it i want to put a transmission temp gauge but i dont know what one my t5 transmission would need or if it even matters. i bet it does and i bet youll tell me.

Manual trans don't need temp gauges

oh
um well what gauge do you think i should get to put in the slot or should i try to get a push start.

NA - OIL, WATER, VOLT, FUEL PRESSURE

FI - A/F, Boost, Fuel pressure, EGT, OIL, Water, Volt

What he said

on a side note I have a Cobalt A/F ratio guage, its a narrow band... pretty worthless but makes cool lights for a NA car...

Its anyones for a beer....

well im getting an sct livewire programmer soon and im pretty sure it has a/f. id like something of some use and im boosting eventually but not for a while and im doin this today. oh snd the livewire has boost reading too. im in a pickle

well if u have nothing....they have one thats a clock...

hahaha yea i know maybe it will just be a hole for a while

just keep it as a switch panel...

yea im lookin at a push start but it might go in my cig lighter spot
