89 Si civic. pulled out the motor yesterday. trying to wire up a non-OBD pr3 ecu while motor is out.

gotta wire up second o2 sensor in pinout C8. accourding to http://www.hasport.com/88-91_Si_SiR_..._convesion.htm, http://b16a.honda-perf.org/wiring.html, and http://tjshondas.20m.com/b16awire.html C8 should be empty. problem is there is a stock wire running to pinout C8 on my car. its grn/wht. now i'm confused and unsure. maybe i'm looking at the wrong pinout. but i looked at 4-5 different times. any got this wire here?

hopefully i can finish the swap and take it to the meet

 

mine wasnt empty either. i just cut it and connected the O2 sensor there. im not sure where the wire leads though. i havent had any problems so far. good luck

 

I also had a wire in that slot and I just cut it and plugged in the secondary O2 wire. No problems so far.

 

thats really assuring to hear. thanks for replying guys btw, i was thinking maybe it has to do with my car being made in canada =P

C12 and C14 have green/white wires in them. If you are counting correctly you should find a green/white wire in C12 and C14. If not, you are probably orienting the plug wrong.

you sure your looking at the plug the right way?, I have both the si and dx 89 wiring diagrham and the only one listed here is a yellow wire and that's only for the automatic equipped civic. make sure your doin it right HTH!!

 

yup, you guys are right. and i'm glad too. guess i was just tired of wiring up the other stuff or something. thanks.
