H23a VTEC Blue Top ECU Pinout - PCF - 37820-PCF-N51
Hi I've got a 1997 Accord LX with the F22b2 non-vtec and I bought a H23a Vtec Blue Top.
I also purchased a PCF ECU which was listed as an OEM JDM H23a VTEC ECU.
The engine also came with the mostly complete Wiring Harness which I imagine is the oem JDM wiring harness. By "mostly there" i mean there's a cluster of wires, maybe 15 or so that are cut.
I have the motor and transmissions stabbed in the car with the JDM wiring harness but when we check the vtec solenoid wire it goes to the A connector pin 15 instead of pin 8.
I have a few questions:
- Is the PCF ecu the right ecu? It says on the side 37820-PCF-N51
- Does anyone have a pinout on that ECU if this is the correct ECU?
Thanks for your help!

have you found anything out on a pinout for this ecu? And yes the pcf-n51 is the correct ecu. I’m having problems with mine using the jdm harness that came with it and I’m needing a pinout as well
