s14 sr20det ecu help

[89s13silvia]

ok so i'm installing a plx ,and they say to install a resistor across the heater ground and power to the o2 sensor so it won't throw a code and go into open loop. Anyway i'm trying to find the pin out so i know which wires these are on the ecu but i'm having no luck

and help is apreciated
thanks
