I'm installing the zeitronix today and was wondering if it replaces the front O2 sensor completly or do I need another bung welded in? Also the simulated narrowband o2 output (purple wire), where does that connect and does it splice into or replace the wire? Same goes with the white wire (wideband analog output) and the blue wire (user input 0-5v). Any input would be much appreciated.
The wiring is the same with the lancer and the evo

Do yourself a favor and weld a bung in the top of the DP just after the transfer case and before the firewall. Don't use the simulator. It trips codes. Wideband output is for a gauge or EMS= don't use. Blue wire is for 0-5v (user input1) which can be unused also. You may elect to connect the blue wire to some kind of gauge or function for logging at a later date. I believe this answers all of your questions.

You are done- nothing else is needed except that extra bung.

 

Thanks for the help. One question on the Wide band output wire..... I have a Greddy emanage, Can I connect it to that? If I can, Where would it most likely go? Also, has there been a final answer in the ignition harness or does it still fry coil packs? Thanks for the help.
