3T-GTE Injector Control

Greetings all,
Im trying to wire up my 3T-GTE but Ive run into some problems. Seems like the injectors wont open and start working. I manually triggered the Injectors and got the engine started for a few seconds, this is obviously not correct. Im wondering what have I wired wrongly. These are my questions.
1. The IG pin on the ECU is wired to the igniter where the RPM signal is output or does it mean ignition where 12V power is input when the key switch is switched on?
2. If I assume that IG refers to ignition and 12V is input here, what does the ECU use as an input signal to calculate the opening duration of the injectors?
3. Currently I know that the yellow wires are supposed to be the power for the injectors, I have supplied power to them directly, 12V through a relay without any resistors (I followed a wiring diagram I found), is this correct?
4. If what I did in Q3 is correct, what supplies the (-) signal for the injectors? On the ECU pins #10 and # 20 is supposed to be the switching side for the injectors. What is actually output from these wires, or is it input signals? Currently mine shows 12V + output, shouldnt it produce (-) signals for the injector?
Do you guys think Im missing any components?, according to the wiring diagram I dont need any resistors or any igniters (to boost - signal). Anybody got any info PLEASE help. Ive been at it for 3 days already, this problem is even creeping up in my sleep!! Thanks!!
