Hello friends .... Sorry my English, I use translator,

hope you can understand me

My 85 Honda CRX. Has the wiring harness OBD0 chopped, and can not use, for the swap
Then I buy a D15Z7 engine from an EK3, better known as 3 stage vtec. Which brings the OBD2a wiring harness.
And I want to leave all engine wiring harness OBD2a, so I think to use the OBD2a engine wiring harness. and connect with OBD2a dash wiring harness all the way to the fuse box, (wich is from an EK3 too) . through the junction connector.
And everything else, lights, turn signal, etc. I Use the original crx wiring, and attach it to the OBD2a wiring harness

It will be very difficult to do? the engine was taken from a EK3, so here would be like having the engine wiring harness as the EK3, but in a crx chassis.

I hope you can help me, greetings to all honda owners.

 

Somebody?

 

There is nothing really much to say. You are going to have to spend a lot of time figuring it out to make it all work. i suggest wiring diagrams and service manuals for both the car and the new engine and spend a lot of time planning it out before taking it all apart.
