air/fuel guage help!!!

ok, i’m having a wee bit of trouble hooking up my air/fuel gauge…its kindda a stupid one(faze brand at autozone) that has seperate wires for it to light up at night. i had no trouble hooking it up…or so i thought…the back light for night lights up fine but no air/fuel stats…:shrug: i tried hooking it up at the ecu and under the hood and still nothing…i’m pretty sure i’m splicing the right wires…can someone tell me how they hooked theres up(and yes i searched the topic already)…like where they grounded, what they splice for power, and which wire for o2 sensor.

pictures are alwase welcome for help:D

never mind…found the thread
