Hey guys I have a Subaru EJ 22 engine. I’m going to try and get it wired up to a Microsquirt. I need some help identifying the wires coming out of the coil pack. There’s three wires coming out of it Yellow, Red, and Blue. The question is... Which one is
12 V positive
Ignition to cylinder 1-3
Ignition to cylinder 2-4
Thanks

Re: Microsquirt EJ22 coil pack wiring question
My guess would be.....
Red is power
Yellow fires the coil on that side and blue fires the coil on it's side.
Now depending on what engine you install it on.....would determine which coilwire goes where.
Since it is a wasted spark coil you would put one coil on opposing cylinders and the other coil on the other two opposing cylinders.
I "Think" Subi is 1342.
Coil 1 would be 1 and 4.
Coil 2 would be 2 and 3.
Which wire fires first is dependent on which wire is # 1 out of the ECU.
Look at the stock install and see how the coil sits....you can then determine which coil goes to which cylinders and figure out what coil is #1.
