Question #1- On the 03 fuel pumps there is a pos & a neg stamped for the wiring. This on the pump itself. Pwr comes from the FPDM, pin 3 & 10. Anyone know which is positive or does it matter. The pump seems to turn the same way no matter which way it's hooked up.
Question #2- The tach signal comes from the PCM on a 95 Ranger. Where does it come from on a 99+ Cobra? Will I have to use a tach converter off the crank position?
Many thanks
