Ok, so here's the deal:
2002 Legacy
99 GC JDM EJ20
2003 USDM WRX ECU
Because it's a 2003 WRX and requires the reflash adapter, but we have all the stock 2002 harness wiring, is there a way to hardwire the reflash adapter circuit into the ECU or elsewhere? I don't think the 02 style adapter is wired in properly to the 2003 ECU.
My understanding is that the 02 has 2 wires and the 03 had 4 wires.
