I have a vx hatchback and swapped out for a gsr. When i was going switch out the O2 sensor i noticed that my vx ran five wires and the gsr four. How do I know which wire splices into what. The gsr O2 has 2 white, 1 grey, and 1 black. The vx has orange, yellow, red, white, and black.

 

Why not just get the GSR four pin O2 it'll look cleaner then tappin into the VX O2 sensor.

 

The vx is a hard one to wire. It also has 4 main connectors on the passanger side shock tower where as all other hondas have 3. You can use 3 out of the five wires from the stock plug and the 4th wire needs a injector ground pulse. Get it from one of the yellow/black stripe wires in the driverside firewall corner. I dont have exact colors as I know there are 2 different looms for the vx and maybe even 3.....Mike
the vx is a pain in the butt

 

The VX 5 wire is a UEGO sensor (wide band) because the car was designed to run lean for emissions. I wouldn't mess with trying to use it, the ECU in the VX has a controller built into it to properly scale the UEGO.

 

oh yes i can agree with this. i still having o2 sensor problems. just dont have the free time to fix it. good luck! let me know what you find. if i happen to find something ill let you know.
