Ok so i startd to mess with the wires on the DX obd2b harnes i got i need to make it work with the B18c motor
I found this

1.) If reusing a CX/DX/LX engine wire harness you will have to perform these wiring mods to this harness:
a) add wiring for the VTEC Solenoid (VTS) & VTEC Pressure Switch (VTPS)
b) perform the IACV mod
c) add wiring for the Knock Sensor (KS) - IF - using an OBD2 DOHC VTEC ecu or non-reprogrammed OBD1 DOHC VTEC ecu
d) possibly extend the 2nd 02 wiring (if you're using a US OBD2 B-series ecu)
e) perform the OBD2a CKF mod


this is what i have done so far

1. I cut/crimp the dizzy plug and and did this wire by wire following this

2. I did they 3-2wire IACV mod just like it shows here
Only one thing in the pic. it shows the 2wire IACV black and green on the JDM harnes is different colors but i wire them proprely (org wire not used ) i did the 2step proces

Now for the KS the one on the harnes is a 3wire plug but on the b18 is 1wire.
Do i just run a wire for KS to the ecu conector C slot 3 ??

Do i have to do a CFK mod ??
am planing of runing a odb1 chipd ecu

The KS is never a 3wire on a honda. Its a one wire straight to C3.

If you plan on running a chipped obd1 ecu then you dont need KS or CKF, thats only for obd2 ecus

Thats the CKF, the KS is on the back of the block.
