hello everyone, I recently bought a Honda Accord 2.3sr. Originally there was an H23A3 engine, which unfortunately knocked, I got an F22Z2 engine. He is already in the car, starting, but after warming up the speed in the range of 750rpm - 2,500rpm, he started the unit for the H23 engine. Now I got a unit for the F22Z2 engine .. its designation is: 37820-P5S-G31. The unit supports Vtec. But my connectors do not fit in the ECU socket. The originals are gray. But the second unit has a blue terminal. Does anyone know if the wiring is identical? I will probably have to compare el. diagrams of both engines. Thank you for reading this far, I will be happy for any reactions and advice.
