ok i am trying to datalog using uberdata and my LM_1. i got everything connected except the .5 volt signal from my LM-1 to the O2 sensor input on my ecu. im using an obd1 p28. and i just need to know which pins to hook my wires to. i got 2 wires(red/white) and a shielded ground comming out of my LM-1. but i know the sensor has 4 wires. i am just confused on how to hook this thing up to my ecu so that i can datalog with uber. anyone that can shed some light. anyone know what pins on the ecu? and which way to hook up? please help

Have you tried doing a simple search for any ECU wiring diagram/pin layout? I'm sure that they must be archived either on this site, or another honda related forum. If you did not want to try and go this route, you could test each pin at the ECU for a constantly changing voltage, which would indicate an o2 voltage input with the ECU in closed loop mode. Good luck.
