I will wait and see. If I can't find a JDM wiring diagram, I might try grounding each of these in turn to see if one of them turns on the Power light.

Thanks for the heads-up

Dammit Joe! Don't you ever read any of my posts? LOL I actually traced the wiring for the JDM TCU in my 94.

The power switch on the JDM car grounds pin 4. The SAME PIN as the economy switch on the UK/Aussie car. If you swap your UK TCU for a JDM one then your econ switch will become a power switch.

If you want a JDM diagram, take the UK diagram and modify it as follows:

(i) The switch connected to a4 is labelled "power" rather than "econ", there is no wire to feed the econ light on the dash.
(ii) The speed sensor 2, being a hall-effect type comes straight into pin a11 rather than going into pin a17, out of c6 THEN into a11. The circuit a17-c6 appears to convert the inductive signal to a hall-effect signal on UK cars. The JDM TCU seems to have this circuit but it is not connected.
