I recently looked at my b18b. and then at my conversion harness from rywire (they converted my dx to an obd1 ls harness) and am a little confused. First, There isnt any wires for an o2 anymore, only a plug.
1. When I buy my o2 sensor, does it come with a little harness? or what?
Ok, now you know that little part the the harness grounds too? there is too wires with ring connectors that bolt the piece that the coolant hose connects too. well on my harness there is coolant connector and I looked under the engine bay of a crv and say that on the b20 there is a plug there? soo...
2. Is this an obd1 thing.
