Clock pod wiring question, need HELP quick

[shamrock 05]

I am wiring my oil pres power to the clock pod.
On the clock pod there these abreviations(from the top down)
BAT
GND
LIG
ACC


(Old Way)I hooked the power into the "LIG" and now the gauge only works when the lights are "on" See the thing is I wired up the gauges and was not able to get the galley plug installed until yesterday. But up until then, when I turned the lights on, everything lit up. But now the only time the gauge will work is when the lights are turned on. So my real question is, which of the 4 choice do I wire it to so that it will get power all the when the car is running. I would think it would have to be wired to what ever wire powers the clock.

(Need New Way?)
Thanks everyone
