Wiring 02 Sensor??

[4g63telantra]

I drive a 94 Elantra with a 4g63T motor.
I have a UNIVERSAL OXYGEN-SENSOR that I just picked up, Just wanted to know how can I hook this 02 sensor right?

02 sensor has...
1gray
1black
2 white wires

How do I know what wires go to where and how can I test the stock harness so I know what wires go where?

thanks

I'm not sure why you think a 94 Hyundai would have the same engine harness as a 1g Eclipse but in case it does here's for the Eclipse:

For 1g:
(From DSM Backup manual for 91 DOHC turbo)
The harness side round connector has pin 1 in upper left, 2 upper right, 3 lower left, 4 lower right.
Harness side: red (pin 3 - goes to mpi relay for power) and black (pin 4 - goes to ground) are the heaters. Black (pin 2 - goes to ground) is signal ground and white (pin 1 - goes to ECU pin 4) is signal.
Sensor side: Every after market O2 has different color wires. The 2 same color wires, usually white (but sometimes black), are the heaters (go either way - they measure about 12 ohms so you can easily find them even if they are not the same color). The other 2 are the signal and signal ground wires. If black and grey, try the harness black to sensor black and harness white to sensor grey. If it doesn't work reverse these two.
