I am planning on swapping a b16 sir2 into civic ex 5th generation. What wire harness do I use since the JDM harness that came with the setup is useless? What parts do I need in the scenario above?

Also, since the throttle body does not contain an external map sensor (built into t-body), how do I work around this ? How about if I was to go with a ITR throttle body?

Anybody have any help or suggestions ?

 

First off, you should have searched this topic, I'm sure there's hundreds of posts on this.

Since you didn't here's some answers.

1- Use you EX harness and add the knock sensor wires or go buy a P30 (USDM delSol DOHC VTEC) harness.

2- Get a 94-95 T-body off a LS or GSR. OR, you can use the 98+ ITR T-body.
