ok i have a obd2 ls motor with the wiring harness will it clip up to my stock wiring in car but not the stock motor harness i know that or do i have to re pin everything

 

is the main harness clips diff then the obd2 harness...?

 

If you have a USDM OBD2 integra harness then yes it plugs right into the OBD1 civic shock tower plugs. 100% plug and play.

 

yes it is usdm LS with the obd2 harness do i have to change any wires or anything cause i dont wanna do this swap and **** anything up

 

you're goign to run an OBD1 ECU i'm assuming? depending on your trim(also assuming you have 93 hatch) you may need to run wires for the 4 wire 02. you only need to use one of them.

 

beat me to it.

 

If you have a complete OBD2 LS swap, drop it right in w. the OBD2 LS Harness and run an OBD1 LS ecu. With work fine.

 

yeah i have a jdm single cam motor in it right now so can i still run the p28...?

 

yeah its a 93 hatch but it is a cx does that make a diff...?

 

Sorta. It'll run, but it wont run right and it will throw codes. Either get a chipped P06 (DX/LX ECU) or an LS P74/P75 ECU.

The CXs used a single wire O2 sensor, The LS and most civics use a 4 wire O2 sensor. You will need to run 2 wires from the ECU to the shock tower. (the signal wire is already there, and the 12v power wire for the heater circuit is only in the engine harness, which you are using from the integra.)

 

its def easy enogh to say but ill take obd1 all day rather be able to tune way easyer at least for me anyway

 

He's still going to be running it as OBD1, just using OBD2 engine components and harness, but with an OBD1 ECU.
