Kod Sol

Ok, so i have a 93 del Sol s, d15b7 motor that I swapped out for another d15b7 motor and trans. I have the engine back in, but cannot locate where the o2 sensor from the exhaust manifold connects to the wiring harness by the distributor, (like on my stock wiring harness)? Is there another way to hook up the sensor without having to swap my stock wiring harness on the new motor? I was looking for the wires that connect the sensor, but cannot find them on the harness. Any help would be greatly appreciated. I don't know if this would help, but the new motor came from a 92 civic/hatch...im pretty sure. which is kind of bad to say, but numbers may on the engine so I knew thats what was most important without having to change ecu's or other parts. thanks

anybody? anybody at all?

possibly its on the back side instead of the front or vice versa. as there any plugs that arnt plugged in?

Kod Sol

um..there are no plugs that are not being used that I can see. the plug has to be near the front since it pugged into the o2 sensor on the manifold, i know the spot where it should be, but don't see the wires. the wires or plug has to be somewhere, I can't see why the guy I bought the motor from wouldn't have used the o2 sensor. im puzzled...ill have to check again when I work on the engine next to see if it is in back. Thanks

Where is your original wire harness?

mono6

it shhould just plug right in..if its the same motor and everything..if not thn you have a different motor i would have to suggest..maybe jus double check again

Kod Sol

I have the original harness, may just plug that one in.

the motor is the same, checked on the block, reads D15B7. everything else plugs/fits right it, just not the o2 sensor. Probably just going to have to install the original one. Thanks
