questions about a few wires

so i just put a 360 in my car and im using the old slant 6 engine harness.
the slant 6 wasnt in the car when i got it...
i have a few wires that are unaccounted for:

positive wire to the coil
oil sending unit wire
and coolant temp sensor wire

wires that are just hanging around:
brown/yellow (long wire)
dark blue (sitting up by the front of the motor)
light grey (long wire)
lavender (up by front of engine)

i think the dark blue is the coil, but im not exactly sure
anyone have any ideas about these wires?
thanks
