Let me translate this into proper sentences before I take a crack at answering this:

Depending on what ECU or Standalone you are currently running, the F10X may be a step backwards as it only controls Fuel, not Fuel & Ignition. As you have a single turbo FD, I'm going to assume that you know what happens when ignition timing is too far advanced under boost (Detonation), so no need to go into why ignition control is important.

As for the harness, it mostly depends on how the previous owner laid everything out when routing the harness. It may just require the proper connectors or you may need to make extensions with the proper connectors. I've not personally delved into the FD's connectors, but there has been quite a bit of discussion on where to source the FD's TPS connector, and I'm sure the CAS connector has received similar attention as well. Chances are that C. Ludwig knows of a source for the TPS & CAS connectors, and could probably hook you up for cheap too. As for implementing them, I am of the mind that such items should be on a subharness utilizing a sealed connector such as a Metripack or Deutsch.

You'll need to change the CAS settings from 24+2 to 12+1 and recalibrate the TPS through Halwin. I believe there is a E/F series 850/1680 map in one of Claudio RX-7's stickied threads. If not, PM him and he should be able to make or adapt a base map for your needs.

As hinted at above, I'd skip it all together and get a full blown ECU. The PFC would be a much better choice for probably not much more money.

It will need to be run in parallel with the stock ECU. So no connectors. I'd say get a patch loom from Boomslang and use that. That will keep you from tearing up a good factory loom. Connect the yellow wire of the F10 trigger loom to the yellow/blue wire at pin 2B of the stock ECU. This is the tach output signal from the ECU and is what will be the RPM signal input for the F10. Then wire the injector outputs from the F10. That's it.

FWIW, as far as any ECU is concerned, 24+2 spinning at half crank shaft speed is identical to a 12+1 crank signal.
