Hey, I am doing a turbo swap into my first gen and need some help wiring up leading and trailing coils? The only thing I have hooked up is the crank angle sensor and have a set of wires from each set of coils not knowing where to plug them into? Any help would be appreciated.

thanks, gabriel.

The large black wires on the coils go to the FC main relay.They are the power lead wires for the coils,there is one for the leading and two for the trailing.The big FC main relay is powered by the FC underhood fuse block,and is activated by a signal from the ignition switch(key).You should use the FC main relay and underhood fuseblock whenever you do an FC engine swap.This will ensure proper electrical distribution,as well as update the old style FB gear.

The leading coil has a yellow/green wire which leads to the ECU.There will be one gangplug on the ECU that will have all the wires on it that youll need to connect,for the left side harness.Just find the yellow/green wire and hook it up.....thats all for the leading.
The trailing will have 3 wires,since its actually two independant ignition systems that fire seperately.Those wires are blue/yellow,brown/yellow and blue/green.These 3 wires will also go to the same ECU gang plug.Just connect the wires by color,and your set.
