I have read write ups. I can get the wiring done w/ my friends help. The problem that The Emmision(ECU) Harness Is PLugged in to the Emmisions(ECU) No problem, but it didn't come w/ the 3rd Plug that goes into the Emmisions(ECU). It is a 22 pin Plug(if I remember). The S4 Chasis Plug is a 24 pin(if I remember Right). I need to find that plug so I can wire it up. Is the JDM the same as the USDM Emmision(ECU) as far as the plugs? What is the Plug called(I believe ithe Plug connects to the wires that are running on the floor from kick panel to kick panel)? What is the Plug for? where can I get one?...or what is the harness that it is on called so I can ask to buy one?
