Thanks for the reply. Well I haven't got as far as starting it yet. The local auto elec got it to cranking stage but there isn't any spark (as expected) I've got the 20V loom in and fitted to the motor, through the firewall and that's it. I need to match the wiring from the engine loom (AE111) to the body loom of the AE92. I also need to sort out the fuse and relay box under the bonnet and the fuel pump in the new fuel tank. So as you can see I haven't gotten anywhere yet with the wiring :(. The AE92 is a standard CX so it had a 4AFC Carby engine in it. I've bolted the ECU into it and as I mentioned earlier, I have a dash cluster from a AE92 4AFE so that I can feed a signal into the ECU from the speedo. Because the AE92 runs a speedo cable I was forced to remove the speed sensor from the gearbox to fit the speedo cable.
