Help! 1G-FE O2 sensor wiring

[headake]

Just got done putting in a 1G-FE Beams VVTI in my RT132 Corona Coupe. The car now runs but I'm still sorting out the bugs. The engine
came from Japan via local importer. It is missing the O2 sensor for cylinders 1, 2, and 3. Someone must have cut this sensor out before shipping.
The O2 sensor for cyls 4, 5, and 6 is there and working. There is also a small wire bundle over the top front of the engine and comes down
the side (exhaust side) that has been clipped clean. (See photo if I'm able to attach it.) This bundle has 4 wires- green, white, light brown(or salmon), and black with red stripe. The green wire is thicker than the other 3 and seems to have 2 separate strands insulated from one another- one in the
middle and the other around it. I have looked at pictures of similar engines and I'm guessing this is the wiring that connects to the missing O2 sensor.
I will get a 4-wire Bosch O2 sensor and need to know which wire connects to what wire on the new O2 sensor.
Please help! Will be greatly appreciated.

the shielded wire is the signal im guessing this is white wire
black red I would say is 12v power for sensor heater
check the second o2 to see if black red has 12v then check the cut black red if it has 12v

brown should be sensor ground

and green should be sensor heater ground

DA, thanks for the quick reply. Just to clarify, the green wire is the shielded one and therefore the signal?
Will check wires for power and verify as soon as I get my hands on a new multimeter.

ok cool
the green one is signal
and white heater ground

Does anyone have a copy of the ECU pinouts for this engine? I've looked everywhere and found nothing other than the one on GIZZMO and it's pretty bare.
Engine is 1GFE Beams VVTI with auto transmission. Thanks.
