MAP GZE oxygen sensor question

Hi guys,
We're wriring up the gze right now (it's a map GZE) and we're up to doing the oxygen sensor.
Here's our questions:
1. How many wires does the O2 sensor for the map GZE have?
2. If I look at this diagram, seems the O2 has only 2 wires, a number "2" going to HT and a number "4" going to OX. I know personally that a 2 wire heated oxygen sensor doesn't exist so what happened to wire "1" and "3" ? Is this an error?
http://www.club4ag.com/faq%20and%20tech_pages/Tech %20Photos/AE92_4AGZE_ECU_2.jpg
For me it doesn't make sense that the O2 pin and HT pin are wired together with a resistance btween them... makes no sense?
If it is an error, what is the correct wiring path for the 4 wire o2 sensor for a map GZE?
Your help with this would be greatly appreciated 
Thanks!
Patrick

that 'resistance' "X" is the O2 Senosaa...
of a 4 wire, 1 goes to signal, 1 goes to power for heater.. and the other two wires are ground (seperate ones).
as for the GZE diagram, i can't help you.
those dashed lines (vaguely off the O2 wires) are shielding (Shiirudo) to reduce interference to the O2 signal.

that diagram isnt quite clear
the ecu has an
ox pin
this is ox signal to the ecu
there is also a ht pin i think which is the earth for the heater
the power side of the heater comes from black with red wire i think
why r u wiring ox sensor
did u not get full loom with it
dont mix the 0x wires up cause u fuk it real fast
