Small update. Harness is almost done other than some of the smaller gauge wires that I didn't have. Pretty simple process to do with minimal soldering.
Engine bay is finally taking shape
I haven't received it yet but I ordered a wiring specialties harness that matches with a ecumaster black along with the ecu itself. I am also having wiring specialties wire the harness for an ecumaster adu5 dash. I am super excited for this to show up.
