Hello everybody .... 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 and dash harness as the EK3, but in a crx chassis.

Greetings to all

You can use the obd2a engine harness in the crx but you will need to rewrite somethings to make it work. You don't need to use the ek3 dash harness so you can save your self the headache of having to rewire two harnesses.
