I am soon to swap a b16a2 into my 98 HX. I know I can not use the 99-00 SI harness it comes with due to the differences in the cabin harness. This leaves me with using the HX harness, the problem is the 7 wire o2. Here is what I know :

Harness side I have 7 wires

2 heater
1 ECU signal
1 ECU signal ground
1 V +
1 V + -
1 V -

I know that the "V" wires will not be used. It appears I have 4 wires left right? Perfect, or maybe not. The colors of the 7 wires are : White, Red, Black, Black/White, Black, White, Green/Black.

Ok..the two black ones are the heater wires. The Green/Black wire appears to be the ecu signal ground. The Black/White wire seems to be my ecu signal as it leads to the Primary O2 Heater Control. Am I missing anything? Thanks for any help guys.
