4 wire 02 @ the harness...
Green/Black...?
Yellow/Black...?
Black/white...?

Functions are...
A6 - O2 heater
D22 - Ground
A25 - Power

which is which?

I also have a question about the Vtec oil pressure switch. My retarded Boomslang instructions (don't reccomend them at all) says to connect only 1 wire to the switch. Well, there are 2 wires going to the switch so I know the other is a ground. does it matter which wire is grounded?

Thanks for any help...

 

The signal pin is white on the 02 sensor.

The green wire on the O2 sensor is your O2 ground.

There are two black wires on your O2 sensor. They are for the O2 power and the O2 heater. They can be connected either way. They are in the same circuit and can't be connected backwards.

You can ground either wire on the VTEC pressure switch. It matters not.

 

awsome...thanks for the info.

BTW...you should include that in the instructions you provide...

I just took a look at my O2 sensor, and these are the 4 wire colors...

Grey, White, Black, Black.

?

 

Green/Gray = 02 ground

 

just looking for help ...Guys i'm going to start off with info on my project.I have a 91 crx si with a freshly rebuilt d16z6 bottom end with p29 pistons,10lb flywheel,etc.
Now i used my 91 si harness with plug changes at the engine harness to gray plugs so that i can use the obd1 distributor, all but 2 sets of wires match up,I have 2 white left over on OBDO and 1 white,1 yellow with a green stripe on the OBD1.which white on the OBDO get's the yellow with a green stripe? this is the big plug we are talking about,the little plug had 2 wires and the colors did match.

Now here's the catch i was told this:
if you look at ur stock wiring harness, there are 2 white wires. You have to look extremely closely to notice this but one of those white wires is bigger/fatter than the other. This fatter white wire goes to the yellow/green wire on the obd1 dizzy. The thinner white wire goes to the white wire on the obd1 dizzy.

This is exactly what i did but what happens is with the 2 white wires still connected the car starts and shuts off within seconds, if i disconnect the 2 wires the car starts and idle's fine, but check engine light is on haven't read code yet cause i got pissed off the car was overheating so i shut it off and been pissed off since!!

 

These colors are for using the OBD1 distributor plug on the OBD0 engine harness.


Function --OBD0 --OBD1
CYPP --Blue/Green --Orange
CYPG --Blue/Yellow --White
TDCP --Orange/Blue --Orange/Blue
TDCG --White/Blue --White/Blue
CKPP --Orange --Blue/Green

this is a cool poast found it on google. I hope the dizzy info is what I needed
