I'm not sure how I can be more specific - so if you have an OEM igniter pack that you want to use, could you give me the pin outs of it and I will draw up a schematic of how it can be used.  That or buy a replacement (or two) IGBT directly from the webshop:

Something has short circuited and caused a massive current to damage one ignition channel, so you also need to find what could have caused that.

Here is a schematic for using a Nissan igniter pack:

As you only need two channels you would use EC36-pin33 and EC36-pin35 and connect the coil pack to their opposite pins.

My car is not a Nissan. It is a Ford Escort RS Turbo. 4-cylinder, the ignition order, and worked with a 1-3-4-2 double coil, one for cylinders 1 and 4, for example, the EC36-34, and another for cilindors 2 and 3, EC36-36.
I suppose it is a mistake it commented.

Good morning Rob. The configuration of my unit, the 868, effectively configured with 4 outputs for ignition, the EC36-10, 24.34 and 36.
It also has four outputs for injection, EC36-6, 7,8,9,17,18,19, and 20.
According to the schedule that you sent me hooked on pin 6 to idle valve. And the FET (injector/WBO2 heater driver) is fried.
Could it be that the cause is not work the ignition IGBT 34 and 36?
Are independents, IGBT -FET.?????

I know that your car is not a Nissan - the wiring advice was for an external
OEM igniter pack, and the instructions I wrote were to aid you to configure
it to drive a wasted spark pack. A fried FET is a very different issue than
an IGBT - the FETs are for switching injectors and solenoids only, IGBTs are
for switching ignition coils - switching an ignition coil with a FET would
kill it very quickly. I really don't know what could have happened to make
your system suddenly stop working. Could you do a File->Save As... in
MegaTune and send me the .msq file from what you have on your box right at
this moment please?

Hi Rob!
I have sent you dates (msq) by mail.
I look forward to your instructions.
Thanks.

Reply sent - it looked like the RPM Limiter had been set to zero.
