I am looking for information on modifying the engine harness in my 92 civic CX to accept a D15B7 out of a DX, I have the ECU from the DX, but not the harness, I want to benifit from the extra 30HP, the D15 B7 has a 4 wire O2 are there any other diffrences?

 

I don't believe there is other than that no, also I know the MAP sensor is different for the DX, it's mounted to the firewall instead on top of the TB, otherwise the O2 and MAP sensor are the only differences that I know of, maybe others know more.

 

thank you much so it looks like i need to get a map sensor for a DX, i looked in the tech archives for a pinout of the cx and dx ecu , looking for a bit better diagram of what i need to change, from the info i got from honda, i will scan it to PDF when i get to work and post it here, maby it can help somone else. it looks like the other 3 wires feed into other sensors, and not the ECU directly, maby i can just splice into the other wires rather than running more. i am a comp tech certified in circut maintance so running wires does not scare me, tearing out the dash does, however i am prepared to do what it takes.
