thats it
its nearly a perfect fit
add the 2 wires and a ground for vtec, add the wire for knock sensor.
its probably the simlest wiring for any honda swap.
you need 2 more wires for the IAB control solenoid.
but it really depends on the engine you have. if you have an H22A1 with the OBDI engine harness, you're set. if you have the H22A4 with an OBDII engine harness, there's a lot more wiring involved.
you'd be best off either using the H22A1, or converting the H22A4 to A1 specs for a simpler drop.
lastly, the A1 uses peak and hold injectors with a resistor box. the A4 uses saturated without of course a resistor box. i cant remember which type of injector the 4th gen Accord uses, so you may have a small wiring fiasco in that respect also, but nothing difficult as long as you know what you're doing.
