Welcome to the site man!

First, be sure that the b20 that you have is from a JDM Accord, otherwise, it wont work at all.

The JDM b20 uses a different ecu, the easiest route would be to swap the entire wiring harness. If thats not readily available to you, (i know it isnt for us over here) then you can add the wire that you need.

You will, however need to change ECU's, or the car wont run right.
