Ok, I have looked EVERYWHERE and found only minimal information, and non specific to what I am looking for. I have 3 main questions, and please feel free to elaborate on them as much as possible. A brief overview:

Original Equipment: 97 Honda Accord LX 4Door.

Purchased parts: B18B1 (Japanese Version) with harness (OBD2 - 2001 Integra LS) (looks modular and was on engine from the crate) and manualtransmission. It also came with P75 ECU.

1. I bought a 97 2 door Ciciv EX harness. My is a 97 4 door. Will that matter?

2. It is an automatic to manual conversion. The engine is installed, but none of the harnesses installed ON THE ENGINE fit into the existing harness. Does the harness that came installed on the engine need to be removed and replaced with the EX harness? Is that what is meant by Plug and Play?

3. Upon inspecting the EX harness (in car ECU side) has 3 plugs, only one fits into the P75 ECU. Was I sold the wrong harness?

Our biggest problem right now is the fact that this wiring is hanging us up. We already have the engine, transmission, hydraulic clutch, cables, fuel line, EVERYTHING is ready to go once this wiring issue is solved or explained. PLEASE HELP! I am so lost, and I have done my research.

It turns out that, according to this link http://www.ff-squad.com/tech/wiring/wiring.96-98.jpg I likely have the DC integra, which is a two piece design. So I guess a EX swap is in order. However, I am still in trouble because the Civic EX harness does not fit into the P75 ECU. It is supposed to be from a 97 civic EX, but only one of the connectors fits the ECU, the rest, I have no idea what to do with. Is there some sort of mod or harness conversion I am missing? I am sorry I cannot post pics, I do not have access to the car as I am posting for a friend.
