ok so i got a 95 civic lx sedan with a smokey motor and a totaled 97 ls integra.

I want to swap the b18b1 from the teg to the civic.

so my question is how do i hook up the secondary o2 sensor because the integra engine harness has all the plugs for the sensor of the motor except the secondary o2 correct?

any information will help, thanks in advance.

You don't, you need to get a 94-95 Integra P75 or 92-93 Integra Pr4 0bd1 ecu to use. You can use your stock mounts, and the Integra harness, axles, shift linkage. 0bd1 doesn't look for the secondary 02 sensor. It's an easy swap.

so quick question, the harness from the integra male plugs will fit in a obd1 ecu than? i was under the impression that the ecus plugs are different because it is for a civic i.e. p28 and p2p have different plugs.

You only want to use the Integra engine harness, not the interior harness that plugs into the ECU. The OBD2 integra engine harness plugs into the OBD1 Civic chassis harness at the shock tower plugs. See pics below for clarity. Credit for pics goes to B18C5-EH2.

94eg8 here again to save yet another life. thanks alot man, now the question here is which ecu should i pick up a pr4, p74 or p75??? are there any major differences within the fuel maps?

one more thing is it ok to run an automatic ecu? i heard of people doing it for d16z6 and y8 set ups but not sure if the same applys to a ls motor

94EG8

It really doesn't matter, fuel and timing maps are all basically the same, honestly you could just chip the P06 you already have with P75 maps.

Shouldn't be a problem, it'll just throw a code unless you convert the ECU.

it'll idle a bit high,high enough not to stall ever.I think the idle also gets bouncy but notsure.
The auto ecu fuel maps are a bit rich too.
Confirm with 94eg8 though he knows alot more than me.

esean93

btw it'll still idle high and run a little rich even after u convert the ecu.the ecu auto to manuel conversion only removes the cel.

alright thanks for the input guys. i'll stick with a manual ecu and now to find a ecu reference guide... i dont have one subscribe too yet.

ok will i found a pr4-a02 and judging from what i searched the "A" means us market, "0" means manual trans and "2" means version.

now is the pr4 a02 a obd0 or obd1? and can i run that ecu with no problems?

94EG8

Correct

Some were OBD0, some were supposed to be OBD1. You'll have to check the physical ECU plugs to determine.

wait obd0 connector port looks different from a obd1 port?

- i just seen a picture of it... i never knew that lol thanks

another swap completed if anyone have question on the swap pm me.

OK I have question about the ecu deal. It says obd2 fits in an obd1 d series tower plug. Will the obd1 b series harness fit the obd1 civic tower harness plug? Any problems with this @ all?

94EG8

OBD1 '94 - '95 Integra or Del Sol VTEC harnesses will both plug in and work just fine. '92 - '93 Integra wont.

Would you have to use OBDI LS dist also?
Or, can the OBDII dist be re-wired to run on OBDI?
I got a OBDI dist for my 96 in my 95 hatch because I couldn't find out about OBDII dist.

kr3w108

OK also which axles would I need. I hear that 94-95 are best fit, others won't work. And for the mount issue. I can use all stock mounts off an integra?
