4-cyl DIS pin-ins

[nacelp]

I'll have to dig, but the 3 pins sounds like the 2.8, that uses the crank
sensor only reluctor sensor.  And I have a pin-out for that.  Gottta dig for
it.  They also reverse one of the coil polarites in the module.
  I don't have a clue on the other but also have data to dig thru on that.
