Trying to find out what the 5 wires on the L1H1 NTK O2 sensor are for, such as which ones are heaters, etc. The colors on my sensor are:
White
Yellow
Orange
Red
Black
This was an engine swap, from obdo to obd1, with a conversion harness and now I need to get the O2 connected to a PO7 ecu which I just obtained. No plugs or harnesses available to me, just wanted to know what the colors on the actual sensor side were for and then I could find the proper pinout on the ecu.
 
Got this from NGK
Yellow: Heater Ground (-)

Orange: Heater Power (+)

Black: Common Ground ( for IP and Vs )

White: IP circuit (Current pumping) (+)

Red: Vs reference (+)

Now, could anyone guide me to which pins these would go on the PO7 ecu?
