Displaying water pressure with Lowrance Engine Interface- 2011 250 SHO?

[Ranger519VS]

I drilled and tapped the adapter for the Yamaha digital water pressure unit and installed a 1/8" barbed fitting to connect the analog gauge tubing. Now the analog gauge and the digital HDS display both show the water pressure. The analog gauge however only shows about 15 psi at WOT whereas the digital shows about 19 psi.

Digital can be off a little and I have heard that quite a few times. Always trust a GOOD analog gauge

Bringing back up and old post as I have done this install but was wondering what the other spare sensor connector marked SSSS is for, is that to add some sore of speed sensor or something?
