First thing... you have a big port (TVIS - This version is shit) = bigport...
Start by identifying the plugs, dizzy , ignitor, injectors etc... They'll need power provided to them.
Fuel pump is via a Circuit opening relay
ECU - needs power to some pins, i'll find a link to a diagram soon and post it up.
Once you have that then you'll have the gauges in the dash to worry about and the alternator, but at a minium there is about 6 things that you need to do to make the car run.
The wires coming out of the fuse box can be used to power the high amp input to the EFI relay... The fuses are powered straight from the battery terminal.
Which in factory configuration is
Ign power to the ecu
High amp power to the fuel pump
Also get yourself a multimeter with a continuity buzzer, and try to track down a datto 1200 wiring diagram and we'll be able to walk you through it.
