Installation on Subaru Impreza  

 

There are a few different igniton options on subarus: 

Installation on Impreza with 4 separate coils on each cylinder 

 

The ECU wiring diagram according to the manufacturer is like this  

 

You need to locate the ignition module and on its 5 pin connector one wire (the biggest one) is 
connected to ground – connect to Launch control GND wire. The other 4 wires are ignition signals 
from the ECU. Cut them and connect the ends going to the ECU to CH IN and the ends to the ignition 
module to CH OUT of the Launch control.
