I recently picked up a Commander 21ft open bow that needs a little TLC. While fixing the trim motor pump, I noticed that 2 wires were hanging out of the lower front of the motor. There were 2 that were connected. After looking up some old parts diagrams, these are the trim sensor wires. Now I did a little Googling and ended up on a site called Maxrules. The wiring diagram doesn't quite jibe with what I have so I thought I would see if anyone could shed some light on the subject.

There appears to be 2 sensors, one on each side of the transom mount. One side has a wire color coded with a white collar and another black. The other has the blue and violet. All four of these have male bullet connectors. The black and white are connected to wires coming out of the harness but the blue and purple are just hanging. The diagram I found shows a white/violet wire so I assume this must be what I see as just white? Can anyone validate this? Here is the link to the diagram I am referring to.
