i did a lot of research
but then again i keep confusing myself when im in process of tapping the ecu plugs.
which is which? colors of the pin plugs to tap?
btw i have a 92 CIVIC CX, and a JDM D15B VTEC swap in it, i already tapped the wires for VTEC, i reused the cx harness, and now i just need to convert the o2 sensor to a 4 plug one..


i did some research and found this..

BLK - Tap A25 or B1 (only tap into the wire, don't remove the one there) - 12V+ Power Input
WHT - D14 (add wire, if pin is there remove it) or you can connect to your old CX O2 wire (if using old CX wire don't remove wire at D14) - O2 Sensor Input
BLK - A6 (add wire, if pin is there remove it) - O2 Heater Control
GRN - D22 (only tap into the wire, don't remove the one there) - Sensor ground

then when im tapping it, i used this diagram

(the 92-95 civic ecu pinout diagram)

please i need help rgith now, i dont know which color to tap, by looking at the diagram and my ecu plugs. it confuses me.

 

helppppp =/

I added the o2 wiring to it, print it and take it outside with you, see if it helps.

 

For the 12v, instead of running it to the ECU, you can run it to the grouping of YEL/BLK wires that end in the engine bay harness on the driver side canon plugs, and tap into one of those.

 

yeah i was planing on tapping that one, the drivers side harness

 

so when im looking at the picture, from the looks of it. the clip side of the ecu is up, and the wires should be from that angle right? im just really confusing myself when taping the wires that clips on to the ecu

thanks

 

oh wait are those the color of it???
like the wires color??
if so GOD THAANKS A BILLION!!

 

Yes, I color coded it, except the 12v which is yellow because I like tepping into the yel/blk in the bay

 

thanks, i just go back from the junkyard looking for a vx ecu.
im going to wire it up right now. ill keep you updated in a few minutes

 

VX ECU? Why? It is mapped for economy, and looks for a 5 wire o2 signal, not good for a D15B.

 

i ran into a few problems now, yeah i picked up the ecu for cheap since its vtec'd. the p28's are more... but then again i need to smog my car.. what do u sugest?b ecu wise?

 

ok here's the problem...

D14 was suppose to be BLUE AND WHITE STRIPS..
mines came out to be RED/WHITE STRIPS..



D22 were good, both blue with green strips..

right when i was tapping the yellow and black strips on the passanger side harness, there were A LOT OF YELLOW/BLACK STRIPS
this is the one i tapped




and oops i forgot to tapp B1, hopefully B1 same color

but i have to eat real quick..
please helpp

am i doing everything right so far?
took a few minutes but this is giving me a headache

thanks

 

P28

 

for some odd reason, my check engine light doesnt come on even without the o2 sensor hooked up

 

D13 is RED/WHT D14 should be WHT.

B1 is an alternate 12v, if you tapped the right wire at the YEL/BLK canon plug, you shouldn't have a wire to put there.

Which ECU?

 

cx ecu for now until i get everything done..

 

ok for now, ill tap the D14 which is white, and dont tapp the B1..
what should i do next? i need to tap one more.

BLK - A6 (add wire, if pin is there remove it) - O2 Heater Control

am i right? thanks for the follow up, i really appreciate it

 

If you have the signal wire hooked up, that's why you're not throwing a code, because the CX ECU only looks for one wire. Right now, till you get an ECU that looks for four, there's no reason to wire them.

 

oic, but then again am i on the rigth track?
everything is looking good so far? anything else i have to change?
ill pick up a stock obd1 manual p28 soon. and hopefully smog wouldnt be a problem since people do pass smog with this motor

 

THESE ARE MY O2 SENSOR PLUG COLORS: WHAT I TAPPED THE COLORS TOO

GREEN- D22
BLACK- PASSANGER SIDE YELLOW/BLACK STRIPS
WHITE- EXISTING PLUG (ORIGINAL WHITE ON WHITE PLUG)
YELLOW- WHERE??? ITS THE HEATER CONTROL BUT CANT FIND IT

FUNTIONS:

D22= SENSOR GROUND
PASSANGER SIDE YELLOW/BLACK STRIPS= 12V
WHITE/EXISTING PLUG= SENSOR INPUT

NOW IM MISSING THE HEATER CONTROL
i tried looking for it on my A6 but then again there's NO BLUE BLACK STRIPS for my A6

so how does it look? it seems right to me, but correct me if im wronge.

thanks

anyone?//?

 

thanks combonator and 92b16vx!!

freaking its orange and black stripss
so im done

thanks for the help, i appreciate it
