Hi, do I need to use all 4 pins on coil pack or just 3? Pin 1 for cyl 1&4, pin 2 for cyl 2&3, pin 3 for 12v supply from ecu.
Thanks
Valeo / Ford 4pin wiring

Strange - I thought all Ford 4 cylinder Coil Packs were 3 pin - 12v in with 1/4 out and 2/3 out ? No idea what the 4th would be for!

Fourth pin on Valeo/GM coils is for noise isolation on OEM wiring.
Not generally used on aftermarket ECUs.
