trim gauge or trim sending unit

[weasel56]

I just bought a pristine 2003 lund with a 03 Yamaha 90hp 4Stroke (F90TLRB).
This is a console model with tach & speedo but no trim gauge and I want to put one in. Is there a trim sending unit on the motor? Do I just need a gauge? How can I get an electrical schematic for this unit?
Thanks, any help would be appreciated.

Depend on what gauges are in boat and the type of wiring harness they have. If the gauges are Lund gauges Lund may offer a trim guage and harness(for Yamaha motor) that would match other gauges in boat. You can use Yamaha 6Y7-83670-40-00 Black face Trim Gauge or 6Y7-83670-50-00 White face Trim gauge and a 6R3-82553-70-00 Trim harness, connects to trim sender on engine and to trim gauge
May need to do some rewiring depending on boat wiring.
