MIL Wire Question

[TnBlkC230WZ]

Is the MIL wire in the GMPP wiring harness a ground source or a power source? I need to know if I connect the other side of the bulb to power or ground.

the ecu provides a ground for the light

See the top of page 5 - "Malfunction Indicator Lamp (BROWN/WHITE STRIPE) – This allows a MIL to be mounted inside the vehicle (there is also a redundant light in the Fuse/Relay center). This wire is grounded by the ECM to illuminate a lamp, 12V must be provided to the other lamp input."

Thanks guys, the eRod instruction manual doesn't state if the wire is a ground or power.
