I just swapped in 99 Si B16A2 into my 96 CX hatch. It runs, but I don't have an A plug to go with the engine harness. Are there any quick fixes for this, or am I going to have to just cut the on off my old motor and rig it up? Right now I don't have any speedo, vtec, and I'm throwing codes for the canister purge valve and the gas tank pressure sensor.
