cryptic labeling on my V8 conversion wiring

[alex e]

WTF is MIL? I'm missing ground and CEL wires coming from the ECM harness. I'm using the Downey manual. I have both 12V wires, fuel pump, VSS, and these two marked MIL. Can't find a ground either on this harness....

I'm confused.

and its a switched ground, not + just an FYI

On older Throttle Body computors they called the Check Engine Light output wire a Check Engine Light wire. On the 1993+ CMFI or Sequential Port set-ups, they call it MIL.
