single wire o2 to 4 wire o2
i am using a stock wire harness from a cx civic to put a b16 in a freinds 92 hatch... got vtec/knock wired up and i am pretty sure i found out how to just hardwire the o2 but i am double checking it here
so far i have the following info
A6-PO2SHTC o2 sensor heating element
Color- org/wht
Battery voltage with KOEO
D14-PHO2S o2 sensor; heated o2 signal
Color- white
.4 - .5 volts when ignition turned on; drops to less than .1v within 2 min.
D22- Sensor ground
Color- green
Less than 1 volt
B1 or A25- IGP2 Sensor voltage; battery positive from main relay
Color- black
Battery voltage with KOEO
Basically let me know if any of this info is incorrect
Thanks for the input

HERE IS THE CORRECT WIRING INFORMATION
ECU - HARNESS COLOR - O2 WIRE COLOR
A6 - ORG/BLK - BLK
D14 - WHT - WHT
JUNCTION CONNECTOR C125 (Drivers side Capped off plug YEL/BLK wires) - BLK 02 wire
D22- GRN/WHT - GRN
Hopefully this helps ; If not, PM me.
EDIT: But yes A25 will work for the other wire instead of the junction connector.
