So I just *had* to go and measure the current draw of this Jetta swap.     ;^)

Power supply relay circuit (ECU, injectors etc.) current draw:

ign. on, engine off, 1.6 Amps
engine at idle: 1.9 Amps, ~ 2.3 Amps at mid low RPM

Ironically, the fuel pump and HO2S drew more: 2.7 Amps.

Since the results were so low, I didn't bother revving the engine up much.

Thanks for the help everyone!

Neil.
