To get your PS pump to actually run, you need to cut the wires that allow the ECU to switch off the PS, as the ST205 doesn't have those outputs.

That does mean my PS pump is active even when the engine isn't running.

which was really useful when I needed a tow from the RAC! The PS also switches off at high speed

(>50mph)

- this is handled by the PS ECU in the frunk and not the engine ECU in the boot.

(They receive the speed signal independently) I did not notice a change in this high speed behaviour when I converted my ECU.

I've not really found the slightly changed behaviour is a problem, however I was thinking the other day that connecting the enable wiring the enable wire to an oil pressure switch would provide a nice approximation to the stock behaviour.

Not really worth the effort to sort that out though.
