How do i wire an o2 sensor on a 51 plate hyundai coupe?

had to change the engine as the big end bearings went in the old one. The connectors for the o2 sensors were different so we had to change the plugs over but the wiring colours are different on the car compared to that on the sensor. On the sensor i have 1 black, 1 grey and 2 white wires and on the car there is 1 yellow, 1 brown, 1 red with a white stripe and 1 green with a white stripe. Need to know which wires go together.How do i wire an o2 sensor on a 51 plate hyundai coupe?

you will have to get new sensors for them to work with the computer.....im assuming you replaced the computer as well? if not you might have to. the engine is probably a year or 2 older or newer and so not all the sensors will be the same. Good luck
