Anybody feel like o2 sensor wiring? (Sydney)

Got a threaded flange to fit generic O2 sensor on the Toyota exhaust 
Got a spankin' new Bosch planar heated-O2 sensor for my MX83 cressida
But Got no electricity in the house to solder it on with 
Anyone in Sydney wanna have a go at it? Throw in some beer or if you like have an extra O2 sensor for free.
Would pretty much involve the steps done by one of our Mazda friends:

I was told by Petroject (called Automotive Service Solutions now I think) here in Brisbane (Bosch distributors and technicians, also do a lot of the dealer training etc for fuel inj systems). They told me NOT to solder the connections for the O2 sensor for my clubbie as the shielded wire is damaged by the heat from a soldering iron, the guy I spoke to said he didn't understand why but those were the instructions they had received from Bosch.
As a side issue, anyone know (have a wiring diagram?) what each of the four wires that go to the O2 sensor for a ST 20V?

jkvsnn - thanks for that reply! I followed up with Petrojet and they confirmed your comment to not solder the wires to make up a new harness. They recommend crimping the wires instead. Too easy.

CRAP and to think i soldered the sheilded wire that is used on my dizzy. It does still seem to work fine though havnt an issue with it so chances are that if you do a smallish job with it, that it might not matter that much.

are they talking about the shielded wire in the harness? i'm about to use double shielded microphone cable (with appropriate heat shielding) for my sensitive sensors.. these can be soldered with no probs..
the 4 wire sensors usually just have plain wires coming off them..
2 wires are same colour = heater.
of the other 2 wires, the black is usually signal, but not for all sensors.

the issue will be that you heat so much, the wire melts thru the insulation and touches the shield.. can easily test with multimeter, looking for continuity between signal wire and shield.
it's probably a "recommended practice for mechanics" as opposed to "recommended practice for people that can wield a soldering iron"
