You can fit a 4 pin 12v dc cdi to your speed fight,all you need to do is cut the pick up wire coming out of the 3 pin plug from the engine the wire is blue/yellow run this to the new cdi box.
There is one feed positive from the ignition switch(this will enable you to kill the engine) one wire to earth or ground and one to the coil,the black side the green side goes to ground earth. And that is it. Simples in it!
Hold the cdi box with the clip at the top now look at the connector,top left(pick up)top right(coil)bottom left(ground/earth bottom right(positive from ignition)
Other folks have said that you need to get rid of the imobi stator because it does not have a pulse gen coil,which is true if you run a 5 pin ac cdi but there is no need for the gen coil with the 4 pin dc cdi box as it will be fed from the ignition. Well people hope this has helped all of you in your quest to get rid of the crap the peugeot have made us suffer with all this time! Beleave"it works!
