Hi this is my first post on here. I've done a wasted spark on my non turbo R34 RB25 Neo with Mitsi Diamante coils and Igniter making a new wiring loom that paired up the Trigger wires that run to the coils with Diodes on each of the trigger wires before they are joined to stop any current going up the wires back to the computer,Make sure you put them around the right way otherwise it wont work at all. Now you have your 3 paired trigger wires (cylinders 1 and 6, 2 and 5, 3 and 4) for your igniter modual IB3 is where your paired up trigger wires for cylinders 1 and 6 go IB2 is for cylinder trigger wires 2 and 5 IB1 is for cylinder trigger wires 3 and 4 **The IB numbers are seemingly backwards because the wires that run to the coils from the igniter from the OC1,OC2 and OC3 wires change colours when they go through the plug on the coil mounting bracket ** THIS COULD BE WHY SOME CONVERSIONS DON'T WORK. VB Plug Needs the posative that used to run to the coil packs posative plugs. GND Needs the earth wire that used to run to the coils negative. TACHO wire is not needed dont connect to anything tacho will still work properly. I did this conversion about 8 months ago when i had my fourth coil pack die and it wasn't under warranty anymore It cost me about $60 for 2nd hand coils and Ignighter from Pick a Part,Solder Wire,length of heat shrink,6 diodes from Dick smiths. I used some wire that i already had to extend the wires as nessisary and some Insulation tape Car hasn't missed a beat since I did this and actually runs better than it ever did on the coil packs has a lot more down low torque. And because I diagnosed the dead coil before I converted I have 5 good coils that I can sell off. I dont know if these coils are any good on Turbo RB's though these coil setups were also used on GTO's Here's a pic of the Mitsi Ignighter
