O2 sensor/Injector wires (?)

OK...I can't find the wire that the o2 sensor plugs into. It is nonexistant. Either that or i'm completely blind.

Question #1:
Can I patch the o2 sensor wire by running new wire from the ECU?

Question #2:
If I can do the patch, which wire is it out of the ECU?

Question #3:
What wires go to the fuel injectors from the ECU?

If someone can show me a diagram of the harness plug that would be cool!
That way, I have something to go by.

sadly, iluvmyrx7.com has been down. it may be back up now or shortly, but it wasnt earlier today (or was it yesterday?).

1/2.) well, the wire to the ecu from the O2 sensor wire will still be there, so i imagine you could just splice it into the existing wire. you didnt say what car/ecu you have, so i cant say definately, but i have a 91 N/A and the plug is 2C for the Oxygen sensor.

3.)
Injector (Front Primary): 3W
Injector (Front Secondary): 3X
Injector (Rear Primary): 3Y
Injector (Rear Secondary): 3Z

i dont have their colors, but looking at your ECU plugs will tell you.
