ok so i've searched and searched been searching since 9:00 this morning and all i can find is how to pin the 02 sensors to the ecu... my question is on what USDM motor do i get the two 02 Sensors off of since i got the JDM B16a its OBD0 with the PR3 ecu and it has two on the exhaust manifold and the Del Sol only has one and the LS only has one so im stumped.... also i have no CEL for the 02 sensor's... will the car pass emmisions with them unhooked? do i need to hook them up?

 

you need to use single wire o2 sensors, buy 2 of them. 88-91 civic/crx

 

so it'll still be the same just get it for the 91 civic which what the car is? but theres the white round plug and the green square plug... i was under ther impression that i could use parts from a del sol vtec and an Integra LS since i found this link http://hondaswap.com/hybrid-ed-ef-da...ts-list-25241/

and here are a few pictures

 

who did your wiring? the round plug i would use as the primary o2 sensor, the second o2 sensor wire it to the secondary. plug shapes don't matter, you can use any plug by cutting and soldering.

 

yeah i know the wiring is all messed up.. it this dude that lives around here... im in the process of getting everything hooked up straight and look decent... but i need to change both 02 sensors what do i get them out of?

 

get them for 90-91 integra or 88-91 civic/crx just get the universal styel and solder the connections

 

i suck at soldering.... but i looked at a 90 Integra LS but i dont have those conections to solder on and i've seen that picture... is there a place online that would sell the 02 sensors i need? should the one from the civic already have the white ciricle one? would it be a good idea to wire the two 02 sensors together?


i might just convert to OBD1 should make things alot easier

 

dont solder any connections. just take a precision screw driver and re-pin the connectors. that all you have to do.

 

ok thanks, i got all that but where can i get the connections because the US doesnt have the green connector and i dont have the wires from the 02 sensors to the plug in

 

go to a junkyard and get a USDM o2 plug, then repin your JDM o2 plug to the USDM plug then get 2 o2 sensors and plug them in (looks like you need to go to a junkyard and cut 2 plugs off from the OEM o2s themselves) then you just plug each one in the correct spot and tada 2 working 02 sensors. if you need i can snip the oem plugs, im goin to the yard tomorrow.

 

ok so just wire both 02's into the white circle plug? if im getting that right just run both 02's into one plug?

 

no, each o2 sensor has a different location at the ecu. hondapartshero gave u the info and you also searched this info... go to the junk yard and get the plugs off any honda/acura wiring harness that is obd0. most use the same style plugs all you have to do is look at the plugs.

 

oh ok so from the two plugs just cut the wires and run new ones to the ECU? and the 90 tegs/civics have the green square plug and white circle plug? ....

 

yes. yes. you can use the purge solenoid plug, it's the same as the square o2 sensor plug... located on the firewall near the map sensor.

 

ok i much appreciate the help on that, so when buying new 02 sensors just get the universal ones? do i have to solder anything?... and the purge solenoid plug will plug right into the green plug thats already in the picture?

 

Autozone has the universal for 19.99 and the plug and play one for 38. If you get one universal and solder the purge solenoid plug onto it it will plug into the green plug. Then buy one plug and play and it will plug into the white circular one. The US integra (90-91) only has one O2 (circular style). If you need the plug for the green sensor and don't have one PM me I'll send you one for free

 

thanks, i appreciate every's help now i just gotta find someone who can solder good, cause i suck at it and i dont wanna mess it up

 

soldering is rediculasly easy.. look up a how to do or something.. but i thought dude said you didnt have to solder it, just re-pin the connectors..

 

yeah but can i re-pin the purge solenoid into the universal 02 sensor? well i take a maintenance class and we learned to solder i just aint very good it would look like crap if i did it aint had much practice at it

 

I dont want to thread jack but why does my b16 with a pr3 ecu only has one o2 sensor? Its obd0 also and its on the exhaust where the end of the header and the cat meet.

 

aftermarket header maybe?

 

No it's stock it's cast iron Honda header

 

hmm i have no clue, but maybe someone on here will know

 

maybe it's a b18 header? that one o2 near the cat is not doing anything for you. the car will run rich, it would be the same as disconnecting it. with obd0, you run both o2 near the head like stock, or it doesn't work. your manifold should look like this:

 

i appreciate that picture i was trying to find where to pin the wires to the ecu and now i know haha
