I have a 2002 WRX wagon with a new EJ205. The car has a few simple mods including AP V3/EBCS. Completing the engine break-in process (@ 125 miles & counting). Running OTS Stage2+EBCS 91 v310 map and using 92 non-ethanol. I need the special wire harness that ties the AEM wideband AFR to the TGV connector & special ROM file. How do I procure this harness & ROM file? Looking at e-tune @ 1000mi.
