Sorry ment 703 controls

Trim,,,,

[Gramas]

Extra trim leads ? Or to allow guage to show trim setting? Or they need connecting to somewhere so trim switch on controls work

should be another loom going to the engine for the trim if my memory serves me, I should have the manual somewhere if you get stuck

The lead I sent you isn't compatible with that box, if memory serves me right that's a later unit.

The wiring colours are slightly different in the later boxes but that's definitely trim wires.

Itl run the engine no bother but you will probably need to jig the wiring for the trim, I'm sure I've had this problem before.

[Gramas]

Yeah it's later box, key choke, what do I need to do?
Will post lead bck mate , drop address in pm
Where do these 2 cables run?
This is the trim guage I have

Don't worry about the lead.

Get a picture of the back of the gauge and il see if it starts the brain going.

You are going to need another trim harness regardless. What's the engine again?

If I'm honest you would be better off getting a new gauge, iirc the newer ones don't do oil level.

[Gramas]

There is 2 leads that run from engine that have the plug connectors that connect to guage, what model of new trim display and leads do I need, I'm complete novice and it's big learning curve

[biffer]

The wires you have, red green blue are for the trim switch and trim motor, you will need to make this loom up or buy one, you will need this irregardless of what you plug into the gauge, if you have a trim switch on the motor this will tell you if that clock is working, the wires are totally separate from all the electronics, I'm still guessing but I've had another cuppa so I think I'm right

[Gramas]

When u say make up , how and do both leads run to engine or one to engine and one to tacho?
If bought new or found 2nd hand it was mentioned oil level loom is not needed ?

That's what I'm saying, this loom has nothing to do with the tacho all it does is work the trim motor, there is a sensor on the engine that goes through the main loom that works the gauge

[Gramas]

So , forgive my dumbness the 2 trim leads have to go to engine? What if I get the newer tacho what looms do I need but more importantly what goes where when wiring to old leads in engine,( colours to colours) guessing game for me

[biffer]

Haven't got enough info. Don't know what looms you have. what engine you have or gauge you want to use

[Gramas]

If I put pics up of looms etc , not sure engine age etc but it's 90 yam autolube , tacho guage would need sourcing, hopefully someone on here can help with that

[Gramas]

Me engine, will get pics of inside Moro, I'd is not on it sadly

[Gramas]

Been told on yamaha forum that one of the 2 trim leads is a spare to add another trim button to boat , think other runs to engine?

The red green yellow black are for your gauges the other red blue green is trim, my advice to you is don't go buying loads more bits until you've worked out what you have already, we have an older engine with newer gauges and wiring loom here, just a bit of fiddling about sorted it

[Gramas]

Will lay it all out tomorrow take pics and hopefully with your help can get me up and running

[Gramas]

I've got old engine, new controls, old guage haha
