Thanks guys...
SVO: too bad, Helms doesn't do toyota.

but no-go.

I'm looking for the common hot to the injectors.
I found links to PDF manuals at Scionlife and now I just need to find the B-R wire coming out of connector 1O (pin 5) on the back of the main junction block under the dash....
If I give up on that I should be able to find it in the engine compartment somewhere before it splits into 4 wires.
hehe
