Toyota Repair: oxygen sensor wiring, oxygen sensor, sensor manufacturer

Question
I am helping a friend that has replaced his exhaust on his 92' toyota pickup (i believe are listed as highlander) 22r  4cyl. He purchased a universal oxygen sensor and being that he did not have the old OE sensor to compare wiring with the question now is what wires go where. The instructions call for a signal wire, a ground and 2 heater wires. He did purchase a 4 wire universal sensor. The question is what wires go where? On the vehicle side wiring harness (female) the colors are BROWN - BLACK - WHITE W/RED STRIPE - AND PINKISH W/BROWN STRIPE. Calling the universal sensor manufacturer resulted in the answer that they have NO colors listed as reference with what I suplied. If you can help it would be great.
Thank you

Answer
I could look up the factory wiring and probably tell you where the wires connect but it wouldn't help unless you had a diagram that came with the new sensor that identified the wires for ground, heater, etc. unless you have this diagram I can't help, if you have instructions scan them and send me a copy to my email address([email protected]) and I'll try to make some sense of this.
