How do I wire the check engine light?

[1moretoy]

Hey guys got the truck fired last night and it sounds awesome. I have auto meter gauges with a billet bezel. I purchased some led lights from brothers to use as the blinkers and the engine light. Each light has a black and white wire. The blinker lights work fine. I have a wire from the harness for the engine light hooked to the black wire and the white wire is hooked to the lighting wire. Did have a couple codes but the light did not come on. Should the white wire be hooked to a power source instead. Pleases advise thank you
