with as many posts as you have
you might know what your are talking about
we have been looking for a keyed 12v source for our
new coil and fuel injection unit.
i looked on U tube on how to change out the ignition key
ie take out instrument panel (few screws)
then one has access to the ignition switch
which we needed to change anyway
and here was an easy way to tap into the
red with green stripped wire you mentioned above.
i plan to disconnect the 'pink' resistor wire from the red/green wire
and hook up a source that has 3-4 plug ins for a 12volt keyed source
then put ignition switch back in and we're ready to go
in the top right of my picture is a bolt with about 3-4 things
hooked to it that were bolted on to the back of the ignition switch
all apparently needing 12volts.
from the wiring diagram
this seems to be the power source to the ignition switch
so would not be keyed, is this right
