Black/Green(double wire) 12V ground
Green/Green(double wire) Lights...to park light wire in column switch(use your FSM)
Red wire...12V constant power(NOT your cig lighter--it's switched)
Blue wire...Switched 12V
I forgot to mention this is 12V only.....on a 24V you must use a voltage reducer
i'm a wiring idiot and will have to have to pull out the dash and take another look. it's not real clear which wires are supposed to go to which from what you mention. hopefully another look will show me the light.
