thechuckster: are you saying there's a special sort of relay for efi fuel pumps? So I can't just use a normal like... horn relay?

you can use normal relays to turn them on/off, but the loom on my 1G-GTE had a 'fuel pump relay' - that was controlled by the ECU and fed from the circuit opening relay for a 12V+ source.
the wiring diagram here on page 1 of this PDF <http://members.optushome.com.au/mkhala/red_celica/ 1G-GTE_info/1g_gte_ecu_wiring.pdf> shows how it's wired up for the 1G - but the principal would be the same (i hope)
depends if you want the main pump to do the 'low power use' thing - but if you think your electrical system has enough capacity regardless of engine revs then don't bother. (But base your highest-current-requirement estimate on a worst case scenario (night-time in rain, passengers, hi-beam, engine under heavy load, etc.)
