The base map shows exhaust cam connected to trigger 2 and inlet cam connected to DI1. There is wiring info in the help file, I will attach below. If you are using a factory loom you will need the relay for the vtec solenoid as shown in the diagram below (since factory ecu switches 12V side), if you are making your own loom then you can do it without the extra relay, connect it direct to an aux output and the other side of the solenoid to +12V.
Oh, be aware also, Im pretty sure the K24 crank sensor pinout is different than the K20, so you need to research that yourself.
That's correct they are different.
Also the K20a from the Accord Euro R (CL7) runs the K24 connector and pinout, I would guess the FD2 K20a might also as it's based of the CL7 engine originally.
