I was putting in my obd2 gsr harness for my b16a2 swap and noticed that one of the plugs by the passenger firewall wont fit...I traced the wires to the ECU and found that they are for the heated o2 sensor off a VX? Should this plug remain unplugged in my swap....? Ill be running a kenji p28 w/this harness....Just making sure so I dont have to go along and redo the harness once the motor is in. Thanks for any input.

 

you're talking about the three engine harness plugs next to the passenger side strut tower right? your obd2 gsr harness should plug into your VX car harness w/o any problems... you're saying that you have an extra plug on the car harness? it might be b/c the VX has a 5-wire 02 sensor and EGR stuff

 

you dont need that extra plug just leave it unplugged

 

Thats what I was thinking.....thanks for the input fellas.....DELETE THIS POST
