Good job on rebuilding the harness. Did yo run new wire all the way to the computer connector or did you splic in near the battery? If you spliced in you want to keep an eye on the remaining old wiring as you may get a short inside the connector (ask me how I know)

You can try rewiring the ETA. I did and got another 6 months before the internal pots died and I had to buy a replacement. If you want a recommendation for a source for a rebuilt ETA pm me.
