D16y8 obd2 swap problems in d15b7 obd1 civic ej2 '94

Hi everyone, this is my first post, I am writing it out of desperation, as I cannot understand why, after completing the swap, the engine reaches 4500 rpm and freezes, it does not go further. The control unit was sold to me with the engine, both belonging to a crx del sol ESI, being an obd2 I had to decode it, the car starts but unfortunately the limiter is at 4500 rpm, this is something that comes to mind is: in the wiring of the engine (also belonging to the crx) I have three orange pins left over, which I cannot connect to the electrical system of the ej2 frame because they are missing, and I think we need a conveyor / adapter 6-3. For the ecu instead I bought the obd1-obd2 converter. Sorry for my English but I'm Italian, I await an answer. 31053
