Fuel Sender wiring diagram for Yamaha 6Y5 gauge

[Creepin_D]

Dealer just installed my new 115 and new tach and speedometer, but I noticed that he did not wire up the fuel sender.

Can someone post a wiring diagram for the fuel sender for the 6YB multi-function gauge?

Thanks!

A diagram would be underwhelming.
The 6Y5 speedometer has several bulleted wires,
including a white and two blacks (the blacks are ground)


The white goes to the fuel sender,
the other fuel sender wire needs to be connected to ground;
either to the remaining speedometer black wire,
(One of the blacks is already connected to the harness from the keyswitch)
somewhere else in the boats electrical system,
since ground is 'common'

why not talk to the installer to fix his screw up

Thanks for the replies everyone, seems simple enough. Do I need to fool with any dip switches?

Also, the reason why I didn't bother with the dealer is because they are located over 3hr drive away.

Quick update, it seems the dealer is using the white wire from my gauge to supply power the "bus bar".

With my old setup, there was a separate cable from the battery to the bus, not it seems he has it from the gauge.

See attached pics, and I apologize for the poor wire management, still a work in progress

Last update I swear haha

Removed that red wire from the white wire going to the gauge and plugged in the fuel sender. Removed fuel sender from tank and function tested it, everything seems to be working!!

Thanks everyone!
