Denny,They contacted me tonight to see if I can help. I have not installed that system check gauge in a few years myself and I dont have the schematic at home tonight. I just cant remember though the wires mentioned dont sound like the colors I recall, so BRP may have altered the color code. Like we talked about on the phone the other day, since you sent in the engine from BRP direct to us and it was not ours, we did not install the gauge or charge for it, nor did BRP apparently provide you one. Marks (Marks Marine) technicians can probably help tomorrow, though Im not sure our crew has that Wiring color code in house. The BRP engines we have hung have the NexSysLink gauges which should function most of the views, through NMEA. The only rig we hung analog gauges on had a 115 on it and we contacted that dealership because the gauges were not in stock at BRP and they installed it. Sorry I cant help more tonight, though I really dont have the answer on the Evinrude question now. Tomorrow Marks crew or ours can get with BRP and find an answer. Rick
