ok here's what iam trying to do.
i have a 1.5 d15z1.... in 92 vx. so i got rid of sorry *** ecu known as p07-a00.
iam using a p-28 non/chip. i changed out the exhaust manifold/ to a 1.6 ex and close off secondary o2 sensor hole. and just using top o2 sensor 4 wire.
but i havent converted to 5-wire to 4 wire.... how do i do it?????????? using my stock harness. got some info but its for a b.18 c.. does it apply to my 1.5 vx harness? also i got rid of intake manifold/w tiny throttle body. and put on a 1.5 d15b7 intake manifold. /w throttle body. no egr,same dizzy/extern coil(msd) cap and rotor. have a solid cel, cause of o2 sensor. i need help to use my 1.6 ex 4 wire o2 sensor. help please searched no luck.....

so far i ran car when i first got it est.18.2 @67mph
with all mods done and no o2 -- got it down to 16.5@ 73mph
next si tranny or will settle for ex.
but i dont want to give up on my mix/match--rotten eg-g.......help needed.thanks

 

some one has some input on my post?????????????????????????????????????????????? ?????????????????????????????????????????????????? ?????????????????????????????????????????????????? ??????????????????????

 

dude no matter how much you fix upt hat motor it will still suck sorry

i have a d16z6 all stock not even intake i ran a 16.4 and im slow as expletive. look at all that work and you're still slower than me. how you ever gonna beat gsr civics.

swap or turbo > modded sohc

 

to trail member? asking for techinical advice on topic.
not you 4 post opinon? (noob)
off subject
its a daily driver. not a track burner

and if you want to talk about boost + swap
i let look into my garage? b18c-sc-jackson???????

Converting 1992-95 VX to 4 wire O2 using VX engine harness

All wires are present except for the power input, but all wiring can be done using the existing wires in the engine and cabin harness. The following wiring will trace the wires, color-coded, from the engine harness side of the shock tower plug to the O2 sensor you are wiring. Most all wires have color changes at each junction.

D14 - ORG/BLU at O2 plug (engine harness side) - WHT (4 wire O2 plug)
D22 - GRN/WHT at O2 plug (engine harness side) - GRN (4 wire O2 plug)
A6 - YEL/BLK at O2 plug (engine harness side) - BLK (4 wire O2 plug) There are 2 BLK wires and either one can make either connection. The second BLK wire needs to be connected at B1 or A25. The easiest thing to do is unpin D16 (BLU/GRN) at the ECU and tap it into B1 (YEL/BLK) or A25 (YEL/BLK). Then on the engine harness side O2 connector, connect the ORG wire to the BLK O2 wire.

 

i <3 the d15z1

 

so what i need to do is d-pin from ecu harness to engine harness.? at shock tower.?????? is that correct?

 

Thanks! I needed to know the same thing. It's weird that VX's keep popping up now... last year nobody knew that much about them. Kinda ironic how the gas prices go up and people take the economy cars and swap them...

Cut the 5 wire O2 connector off first. Then you are left with 5 wires.
Check the wire colors at the connector for your 5 wire O2...the colors on this list should be in there. All you do is follow the instructions for the first three wires...you should then have one black wire left over. Hook this black wire up to the orange at the 5 wire O2 plug, then go inside at the ECU, cut the blue/green wire at D16, and splice it into the yellow/black (pin B1).
So:
D14 - ORG/BLU at 5 wire O2 plug (engine harness side) - WHT (4 wire O2 plug)
D22 - GRN/WHT at 5 wire O2 plug (engine harness side) - GRN (4 wire O2 plug)
A6 - YEL/BLK at 5 wire O2 plug (engine harness side) - BLK (4 wire O2 plug)
ORANGE at 5 wire O2 plug (engine harness side - BLK (4 wire O2 plug)
Then, cut BLU/GRN at pin D16 and splice into B1 YEL/BLK.
5 easy steps.

 

the only problem with running the heater power through the blu/grn-orange-black wire (it changes colors in the harness) is that it resides in the O2 shielding. that defeats the purpose of the shielding.
running a seperate wire is the way to go for the heater power. (run it to the yel/blk wires at the driver's shock tower)
to be a purist you should run the ground wire as well, heater ground should be a power ground and not a logic ground like that yel wire is.
run the grn 4-wire O2 sensor wire to the ground wires on the thermostat housing.

 

If you are running a chipped ECU you can always disable the O2 sensor heater as well.

 

do i have to use a four wire O2 sensor? cause the one i got has a crack in the tip part of it. is the any to by-pass it some how? 1 more thing when i de-pin o2 sensor plug i found t a jumer of some sort in plug off the 5 wire o2 what could it have been used for? its look like a mini fuse but it's not .also it was black. ?2 pin jumper i think. and a cel of 5 long flash. when do you when test of check engine light. is done need help/

 

bad 02 need help? what to do
