Re: Door ajar indicator through rear vs front lever light

["content22207" <brobertson@xxxx>]

Your red line diagram indeed correct for REAR lever light, which is
not diode isolated.

Just re-read Patrick's original post: does NOT state which light he
was flipping. Assumed it was front, but could be rear.

If Patrick in fact flipping rear light, you are correct (would also
work with ground continuing through purple wire junction under console
to hood or engine compartment lights BTW).

If Patrick flipping front light I am correct (that's third diode right
above delay module in wiring diagram).

Re: electricity as diode -- if purple line into door lights was live
your red line diagram would never find a ground after them. This is
the same principle used by those of us with 4 way turn signal mod
(different circuit of course, but same idea).

Re: pulling fuse #12 when doors open -- car usually not energized. Key
could be in accessory position to play radio etc, but NOTE: then makes
no difference whether fuse #12 in place or not! Indicator light will
ground itself through door plungers as usual. Is only a problem if
fuse #12 out *AND* both doors closed *AND* you try to illuminate hood,
rear lever, or engine compartment light.

Re: "would be physically impossible to ground indicator through their
individual grounds WHEN FLIPPED IN THE OTHER DIRECTION" -- you
conveniently removed end of that sentence before replying... Takes
totally out of context! Please show me a 12v circuit that can
physically jump lever light gap when flipped away from its ground.
