Ok guys, I have posted in the EG+ forum and no one seems to know. I have just a couple of questions.

I have a 1997 Civic DX hatchback and am looking forward to swapping in a 99 ex head. So far I have the head, internals, and intake manifold. I am planning on getting a 96-98 p2p ecu from an ex. I am also getting a new headgasket (y8) valve cover gasket, and timing belt. My question is would I need to get the ex wiring harness for it? Or is there a way I can run custom wiring on it and have it not throw any CEL's. So far I know of three wires: (1) Vtec Solenoid, (2) Vtec psi, and (3) knock sensor. Does anyone know if there are any more wires that I am gonna need to run? I already know i need a knock sensor from an ex or any b series engine to put somewhre on the block to avoid the knock sensor CEL. I am unsure about the secondary 02 sensor problem though. I heard from someone that if you use a p2p ecu, you will run into problems with either the primary or secondary 02 sensor CEL. The reason why this puzzles me is that if im not mistaken, the ex and dx/cx/lx both have two 02 sensors, one in the exhaust manifold and one in the catalytic converter, the only difference is that the dx/lx/cx have the cat mounted vertically right by the exhaust manifold. Any help would be appreciated.

Cliffs notes - doing a y7 to y8 minime. What do I wire up (what wires, #of wires) to avoid any CEL's.

 

anyone?
