Experts, can I replace my original unit with this one?

The Dieselview drives the gauges. If neither the Dieselview nor gauges work then probably a systemic issue with the harnessing or connectors or a failure within the Dieselview unit (but unlikely). First swap the CAN 1 resistors (yellow capped connectors on the helm J-boxes and see if the problem follows to the other side. Then swap the CAN 123 resistors on the engine harness (yellow capped connectors on the engine harness' and also see if the problem follows. If the problem follows a resistor swap then a defective resistor. If the resistors are ok then swap the port and starboard engine main cables (circled in the below diagram) coming into the helm at the J-boxes; they should be the large yellow cables that terminate into two J-boxes under the helm. If the gauge problem follows that swap then the issue obviously exists between the engines and the end of that yellow cable. If the issue does not follow then the issue is between the J-boxes, Dieselview, and gauges.
