Convert 150 four stroke to Analog gauges

[billyboatsandbeans]

My digital tach and speed meters are now nearly impossible to read. I would like to convert to the analog gauges.
First will the signals from the engine to the digital gauges drive the analog gauges?

Then I need to know what wires drive what. I know:
Yellow is - ignition power,
Blue - lighting
red unswitched power and probably not necessary with analog
Black - ground

Then the Tach has two connectors
connector A contains wires:
Pink
Tan
Grey
Black with white tracer

Connector B has wires:
Green with red tracer
Green with White tracer

The speedometer has a white which appears to drive the fuel tank level.

Can anyone identify what Wires drives the:
Oil Pressure
water temp
Trim
Fuel level

Don't know what year model you have, model number would help.
If you use Yamaha four stroke analog tach and Yamaha analog trim gauge then it will plug into harness you have.
Yamaha doesn't offer a analog oil pressure gauge, tach does have low oil pressure warning light.
Would need water temp gauge and temp sender.

Converting to analog gauges

The motor is a 2004 F150TXR

Thanks for the information.
I was hoping to use Faria gauges as they have a four in one unit. Maybe there is a place to install an oil sending unit and temp sender so I would have actual gauges instead of oil & temp warning alarms.

wont work.
the visual indicates in the tach are set by signals from the ECU.
yamaha makes a combatible analog tach with the visual indicates.

faria?? isnt that how you spell junk in italian?

digital to analog swap

Thank you.
I do believe I can add a temp sender and oil pressure sender with wiring and get what I want.
I actually dont know anything about Faria. I just seen that they offer a four in one 4" gauge that would fit my dash very nicely. I couldnt find this with other manufacturers. Hope not to buy junk, I like quality.
