i have a 96 dx hatch, with a ls/vtec gsr head. i just picked it up, and one of the problems with the car is that it is throwing cel # 65, which is secondary o2 sensor heater wire. so i thought maybe the sensor came unplugged. So i got up under the car, and i find the sensor, with the plug hanging there. My question is that i cant find the OEM o2 plug ANYWHERE, i searched on here, but couldnt come up with where the wiring for it comes from. I read somewhere that it comes through the floor? is it not connected to the main harness. any help would be great.

thanks

 

bump, there is no where in the floor that it can go. 96 diffirent than other years?

 

who did the swap and wut engine harness r u using

 

i thought it was only the EX or SI that had the secondary o2 thru the floor..
on the dx/lx it should be part of the engine harness.. it should be next to the primary o2 connector. atleast thats how it is on my 96 lx.. they have identical harnesses.
