how can i make the 1 wire o2 sensor work on my 5 wire harness?

 

What are you doing ?? swaping the engine ??
are you using the same VX Ecu ? if so you dun need to swap to a single wire o2..
If your doing a swap that has a single wire o2 and your using the single o2 Ecu then all you do is wire the single o2 to the ecu ... check hasport.com to find which ecu pinout you need to wire the single wire too ...

well if you are trying to go from a 4 wire (heated o2 sensor) to a single (non heated) it's just not gonna work unelss your chnaging to the proper ecu for that o2. the difference is one is heated one is not a single wire will not work with a 4 wire harness you need to go buy an o2 sensor
