Help. MPGuino not powering up in car. USB o.k.

I just finished installing my new MPGuino kit from

The installation is pretty easy because the ECU is right under the driver's seat which tilts back out of the way.

Everything is now sorted out except for fine tuning the numbers and building an enclosure.

This is on a 1993 Toyota Previa but I think they are all similar.

ECU is under the drivers seat. Red is the injector wire spliced with a black wire in pinout 12 connector B (top connector on ECU) . Black is the vehicle speed sensor spliced with a purple wire with a white stripe on pinout 9 connector A (bottom connector on ECU).

Found 12v+ unswitched under the dash below the steering column. White wire with red stripe. I grounded to the body.

Any questions?
