i have a 1999 F-150 4.2 liter. i am trying to install a tach but there is no cylinder type coil that i am use to. i know i need to hook the green wire to the coil pack, but what and where are the coil pack. Where do i find a connection for the green wire. thanks to all

 

FORD, F SERIES LIGHT DUTY, 1999, Tachometer

Tach wire: on the 4.2L it is a dk. blue/lt. green at the coil pack on top of the motor. On the 4.6L it is a pink/white in a 3 pin plug at the front of the motor below the air intake and next to the fan. On the 5.4L it is a lt. green/white at the coil on the passenger side of the motor between the fuel injectors.

 

thanks Frostby
