How much current (voltage as well if you know) does the mil pin on the pcm support? I am doing a project and need to use a relay but I dont want to destroy the pcm by running to much current through that circuit back to the ground that the mil pin on the pcm applys.

 

Ignition voltage 12v feeds the logic to the LED MIL.
LEDs are 1.5v and do not draw squat.

Would the PCM driver support a 194 or 1895 bulb? I don't know for sure but
I'm getting 411s cheap enough I might just try it.
Surely someone in conversions\hybreds has done this
