Default Water Level / Senders

Hi experts,

I am facing an issue since almost 2 days, and can not figure it out. On my 270 I don't have water gauge so I decided to install one.

Boat was all analogic and I have decided to convert it to Digital as the Engine is Smartcraft Ready. Everything work as it should except for senders.

What I have found so far is that on Merc you have two wires on the engine (Fuel 1 and 2) one pink/black and the other blue/white.

I have been able to have the pink black working so Fuel 1 senders is read by the engine, but not the water sender.

I wanted to be sure, so I have put water gauge on Fuel 1 (Pink Black) and Fuel tank on Fuel 2 (Blue/White), infos from water tank are ok but then the second gauge is not able to read anything.

I definitely have a problem with the second wire on the engine. Question is : Do you think it should be enable on the ECM ? Anyone have done this before ?

I have plan to brought the boat to my dealer but I am not so confident that he will be able to resolve this.

Thanks guys.
