Ok I just finished putting a b18b out of a 97 integra into my 95 del sol. I used the obd2 engine harness but used an obd1 ecu. When I was putting everything in I noticed there was nothing going to or from the sensoron the bottom of the throttle body. I believe its the intake air temperature sensor. Does anyone know where the coolant lines for this sesonr feed from and to? Also I threw a CEL and noticed when I jumped it I get one long flash or 10 which is low and behold the intake air temp sensor is what I have read on this site. A picture would be great if someone has one...Thanks
