ok my friend and i have got a b16a1 going into a 92 integra gs. Now everything is good to go except the wiring... We are using the cars obd-1 harness, with a pr3 obd-0 ecu. we have a frog harness for the ecu to hook directly into the wiring which already has the 4 v-tec leads on it. THat isn't our problem. Our problem is that the b18 that came out of the car had only 1 02 sensor. It was connected by 4 wires. WHile the b16 manifold has 2 02 sensors each connected by 1 wire. what in the heeeck do we do to connect these properly and lead them to the ecu??? THERS 1 other problem .. the b16 block has a 2 prong sensor on the back side just under the knock sensor.. while the old b18 block didn't. WHAT is this new sensor and how do we wire it to the ecu as well???? thanks!

 

why didn't you get an obd1 b16? you would've been done already. this should help.

http://www.g2ic.com. got to teg tips under engine.

 

well.. the motor is here and really it was all about cash and the b16a2 was more than my friend could afford at the time. and with the blown up b18 not doing him any good he went this route. I've been to that site and it has absolutely nothing on what im looking for. All i essentially need is wiring for the o2 and that sensor on the back of the block... :S

 

the sensor that your talking about is what makes the fans tuen on
it senses the temp of the colent and when it reaches a certain temp it will swich on the fans

 

oki now to find where to shove that into the ecu....
