97 hatch with 98 si motor ?'s

[pappaj]

I just bought a 97 civic hatch cx, it came with a 98 si motor, complete si harness and ecu, I need to wire up the secondary o2 I'm just wondering if anyone knows where the pin locations for the secondary o2 is in the plug, I think on the the driver side strut tower.

I have the ecu pinouts but I would rather come off of that plug then run it all the way to the ecu. Any help appreciated.

This swap seems simple at first glance but it is becoming a pita, fast. Now that the car is running I have two cel's one for the secondary o2 (expected) and one for the fuel tank pressure, which the cx hatch doesn't have a ftp switch, lots of fun.

you could do that ,but it better and easier to run it off the ecu..
