I'm upgrading my trim tab switches with ones that have led position indicators on my 97 bayliner 4788. Has anyone else done this? I took the switches out of the panels and the only wiring seems to go from one switch to the other. No power connection and no harness to the pump. Does anyone have a wiring diagram of the original installation? Any other thoughts?

Hey Bayjon - here's the link to the EIC5000's which will do what you want . . .

Put out a call to Tabman . . . he's the Bennett rep on here and he's on here quite a bit helping out those of us who . . . well, have problems. He's helped me out a lot . . . . can't go wrong. :cheer:

Whoa!! Just reread your posting . . on a 4788? . . ouch, don't think what I said was right . . . let Tabman advise you.

I am assuming they are Bennett, correct? Is this at the lower, upper or both stations?

Here is the back of a Bennett switch. Power is connected to any of the terminals on the strap marked "+".

Tom:

I .want to chase the wiring from the pilot house switch and the fly bridge switch to the power source at the electrical control panel. There is a junction box somewhere that the harness from the hydraulic pack connects. I can't find it.

This would be to the Bayliner 4788

The 4 color wiring harness runs color for color between the upper and lower station. Normally the connections are also made at the lower station to bring power to the system and then run to the Hydraulic Power Unit.



But it does not sound like it is the case on your boat.

Orange wire at the back of the switch(es) is the power supply for the Bennett HPU. Usually connected to the battery on a smaller cruiser, may be connected elsewhere on your larger 47
