Default 2015 DF115A wiring harness/NMEA2000 data?

Hi team

Scenario as follows:
2015 DF115A’s (twin rig) running standard Suzuki analogue gauges.

Outcome wanted:
Owner wants to add engine interface cables so engine data will show on his MFD screen. Wants to keep analogue displays operational at the same time.

Question: is there now an option to connect the interfaces directly to the harness behind the dash, and also be able to keep the analogue gauges running??

My understanding was that in those circumstances the interface will have to be connected to the SDS plug on the engine using the SDS adapter cable?

would appreciate your advice. Thanks!

Yes sir, you are correct . The only way to run an analog tachometer and get NMEA 2000 data info on a Multi Function display is to run the engine interface off of the engine diagnostic port on the motor into the Electronics N2K network and leave the tach plugged into the Suzuki 4 pin harness under the dash.

Thanks Mike for confirming that for me.

Had a THT and Suzuki forum member trying to tell me that his analogue tacho definitely worked at same time as he had interface cable plugged into main harness under the dash and the engine harness plugged into SDS port..

I suspected he was full of - - - - and you’ve confirmed.

I think his mechanic must have run a long version of the SDS adapter cable up to the dash, where the interface was then connected.
