I am unable to understand following Pins.
A2 MCS
A3 2WBS
A4 VSV
A5 CRS (may be cruse control solenoid)
A6 PCS
A9 VSSOUT (does it goes to cluster?)
A28 SLU

 

What is this for? Year, model, trim & engine?

A2 = Engine mount control solenoid valve.
A3 = Drives EVAP bypass solenoid.
A4 = Drives EVAP control canister vent shut valve.
A5 = Cruise control signal.
A6 = Drives EVAP purge control solenoid valve.
A9 = Could go out to a junction box, that sends a signal to the cluster, cruise control and A/C... I'm not 100% sure as you have not listed what vehicle this is for.
A28 = Detects interlock control unit signal

 

Car is CB1 JDM Accord with F18B VTEC with OBD2B ECU

 

If your car is originally an obd1 car and you're using an obd2 ecu then you need to have a crank sensor and crank timing pulley for an obd2. Do you currently have one of both installed?

 

Actually I have ODB2B wiring and F18B engine which has CKP and CYP sensors.

 

how did you wire in the CKP and CYP sensors to your existing harness ?
