Re: b18c swap
Just use your harness as it's almost identical to the Si harness with the exception of the CFK plug and distributor plug. You'll have to do a few wiring mod depending on what ECU you use and if your B18C is OBD1 or OBD2. List those and we can help you on how to wire it.

Is it a JDM motor? Is it a JDM ECU? Is the B18C the type R engine or the GSR engine?
Can you post pics of the engine and the ECU including the label?

Re: b18c swap
Use your harness and get an OBD2b to OBD2a distributor adapter. As long as your ECU is JDM then you don't have to worry about the CKF sensor. For you intake air temp sensor you'll need to put into your intake arm. Check out this thread I made
