Default obd1 conversion

I got this harness my buddy gave me from Zerg Inds and im doing a obd0 to obd1 conversion.Im having a little problem, ok now im reading the pager it came with and im getting confused here:

blue: po2htc o2 sensor heater control (02BLK wire)
white: ph02s o2 sensor signal (o2 white wire)
violet: vts vtec solenoid signal
gray: vtm vtec pressure switch signal
green: iab intake air bypass signal
orange: knock sensor signal
red or pink (2): icp power (iab, o2 black white)
black or brown (3): pg ground (scs, vrm, o2 green wire)
yellow: scs service check signal

installation notes: iab is only used on certain engines and only looked for by certain ECU's (P72 & P13), for all other applications, it is not required.
SCS is used to check for the sensor codes. A toggle switch can be placed between the YLW wire and the black wire, or directly to a ground source. If you choose this options, keep the YLW wire covered so it does not make contact with anything that may activiate the SCS.
IGP and PG (power and ground) connections are only recommendations and active locations on the ECU. Other locations may be used.


Now, what I'm confused about is which ones do I use for the o2 the black or the brown? or the red or pink? and right before this it says to connect the black and yellow for the CEL. Everything else I'm fine with I'm just stumped on this
help plz!! need to get this done tonight !!

Default Re: obd1 conversion

use either the red or pink (pos+) those not matter just pick one, they will both do the same job.
same for the black & brown (neg-).

put a toggle switch from yellow to black, this is for when U want to check for engine codes.

I have the exact same jumper !!!
