I'm trying to put a civic DX motor D15B7 in my 92 civic CX. My civic has only one O2 wire. What I'm trying to figure out is if the wire harness from the DX will "plug and play". The CX is an ECU PO5 the DX is an ECU PO6. Are these compatible?

 

For the swap, you need the P06 ECu and to run additional wires for the 4-wire D15B7 O2 sensor.

 

If we're using the engine harness from the B7, do you still need to run additional wires? If so from where?

 

Nope.

Do you have the B7 IM and throttle body?

 

What's the IM?

 

I have the entire engine. I have the throttle body, not sure what the IM is you're talking about though.

 

Intake manifold

 

Yes. I have the total engine, wiring, harness, and computer.

 

Plus the IM. So I should be able to just do the swap, and plug and play?

 

I think you should be good to go.

 

Thanks my good man.
