Yamaha 733 control wiring

[Gramas]

Right I now know the light blue, green , and red loom from controls is for extra switch and can forget about it!!!
So will get pics today of the two leads coming from engine that have connectors on that plug into lcd marine meter!
Also have 2fuse harnes that links loom from 703 control throttle to tachometer!
I think from what I've found out guys on yamaha outboard forum I may be alright??? What you think????

I've had a look at some bits in the office and the new control loom might have some trim wires in it and you could be right that them others are spare, I can't see how this will help you though as your engine is still older style.
Just plug it in before you mount it and see what works

I also have found a few gauges will let you know later what I have

[Gramas]

Ah great will take photos today of what I have

[Gramas]

Was sent this from yam outboard site

Yes that's what I found in the office late last night, have you got that second loom that goes to the gauges. Have you got the plug on the outboard to plug that second loom in

[Gramas]

Will need to take closer look but I know that aswell as the main 10pin cable there is 2 small leads one is flat they both have the push fit connectors that match into the guage I have

[biffer]

Half way there then, plug it all in where they fit and see what happens, take it from there

[Gramas]

So you think I might be ok in terms of needing new guage n looms

[biffer]

Plug it all in and try it, we could talk and check to the cows come home but that won't get the answers you are looking for

[Gramas]

Will do and cheers for your help biffer hopefully I can get it going, in gauges do u have a newer type? Think they have trip timer etc on aswell as trim guage

[Gramas]

This is what I have

Back of tacho close up

I think I'm going back to my early posts, most of that is not compatible without a bit of wiring, MHO. I don't think that you will get this working without a visit from someone, I hope I'm wrong for your sake, but it looks like you'll have to go through that a bit at a time

[Gramas]

well with new controls i know the 2 fused harness will defo connect to it then at tacho end i need the bullet type connectors as these are missing!
there is the trim lead and another which look as though they should connect to tacho but time will tell
