Wiring Diagram for Trim Sender Unit
 

Does anyone have the instructions for Trim Sender Unit 863187A2? I am looking to see which what red, blue, white are, thinking red is 5v but unsure what is ground, and signal ? I just need the function of each wire as I am wiring this into my standalone engine / digital dash.

when i did a search for that part number it shows its used on the following:

• BRAVO XR ONE - 0W240000 & Up
• BRAVO XR ONE - 0L914990 THRU 0W239999
• BRAVO XR SPORTMASTER - 0M906878 & Up
• BRAVO XR SPORTMASTER - 0M052945 THRU 0M906877
• BRAVO XR THREE - 0W240000 & Up
• BRAVO XZ ONE - 0L914990 THRU 0M999999
• HI PERFORMANCE TRANSOM - 0W150003 & Up
• INTEGRATED TRANSOM - 0M052768 & Up
• INTEGRATED TRANSOM - ALL THRU 0M052767

i have a manual for the XR with ITS and it shows that plugs into a control module and doesnt give function of wires...

Red is +5 volts
White is signal
Blue is ground

thanks!

If your trying to connect it to a analog gauge then you need the Merc digital to analog converter. I tried this a few years ago and the box doesn't work

From my notesThe old part 845060A1 is the old kit which is no longer sold. The new part is 884359T1 which is the same as the old part but does not have the screws and spacers.
