It's an oxygen sensor, don't worry about the wires not matching up on either side of the plug, Toyota like to do that to confuse us....

from the sensor there is white wire , blue wire ,and two black

from the motor there is brown wire , black with red stripe , black with white stripe and a black wire inside a grey wire

from sensor, two black wires are heater wires.

from car, black inside grey is probably sensor wire.. i forget the rest

search for oxygen sensor here and there is a link somewhere to eric (fahlgren?)s site which has wire colour listings for many makes of cars and their sensors

yeah i looked at his thread and the wire colours dont match.... so any ideas?
