ehhhh.. I dunno about the Si harness man. The OBD1 distributor has 2 plugs, OBD2 has only 1. That's the huge difference I believe. The injector clips are different too, but that's an easy fix...

 

i know that the 94 harness is obd1,but what is he going to do for injector
plugs and among other wiring connections.if you have done as many swaps as
i have done you would know what i am talking about,maybee i didnt explain myself fully enough for that i am sorry.but name the swap ive done it,i am currently working on a k series swap into a 99 civic si which is 60% complete
waiting on harness and axles from hasport.have lots or pics and will post.

 

The 94 Teg LS engine he got came with a 94 Wiring harness complete. But if we use that what would be the point in the wiring adapter? I need info from someone who has done the swap so I can know exactly what to do and such.
Thanks

 

PM me with phone #.

 

You're talking about two different things here. The Engine harness runs from the sensors on the engine to the connectors at the strut towers (which an OBD2 Civic doesn't have). The adapter just runs from where the ECU would normally plug into the ECU harness to the ECU. It changes the plugs so you can plug an OBD1 ECU in. They're 2 different things located in 2 different places.

 

I'd keep the chassis harness, and just change the plugs that won't plug in (dizzy, injectors, evap, IAT, Alternator.)

And then extend any sensors that don't reach (IAT, CLNT).

I dunno, it's not really that hard, it's just a matter of being comfortable with it.

Also with the DX, you may have to go from 3wire IACV to 2wire.

Sorry to bring up this again. But where are all those sensors located. I found the dizzy, injectors, and alternator. Where are the rest of them? Like what do they connect to like what part of the engine. Thanks
