The water pressure gauge won't work. I've tried 2 different gauges. The gauge before and after theWP gauge in the daisy chain work just fine. Any ideas?

Has it ever worked? Did you OHM out the sender?

Don't you have to "configure" those CANBUS gauges so they all match the "starboard" (or "port") setting on the motor?

Neither gauge ever worked. All the rest work just fine. I did not check the sender, any idea where it is on a 150 4 stroke?

Probably does not have a water pressure sender installed. 150 4s don't come with them, you have to buy separately and install yourself. There is a pigtail in the main engine harness for it, but its just capped off.

Thanks! Where is the pigtail located?

Exhaust manifold area. Right where the sensor goes

Right under the alternator?

Thanks, I found the pigtail and the plug where the sensor goes.
