I'm not sure if your still active, but I'm seeking help doing a harness for a gvr4 link ECU to Evo 3 harness Inc mfi (not sure whether to use e123 mfi or gvr4).



I'm using a cut up gvr4 engine harness and have a e123 harness so have all the plugs available.



If you can help I would really appreciate it



Thanks



Phil
