Broke but no Joke
can anyone help with this? I swapped the b18b1 in my 93 civic which had an aftermarket exhaust and was obd2. somehow the harness i bought with the swap just doesnt have the second o2 connector... If anyone has a semi easy to understand diagram of the 99 ls b18b1's harness or knows how this is done your help would be much appreciated!

Thanks-8)

I need to wire up this o2 sensor... anyone? can someone with the same motor look at the wires coming off the o2 sensor and match the colors to the ecu? I just need to know which holes to pin...
