Does anyone have a wiring diagram for the 6y5-8350t-83 tach ?

You don't see the wiring diagram that you asked for?Originally posted by Joediveguy View Post
Only talking about 12 short wires. About 10 inches long each I would guess. Four each to a nylon four pin connector (two connectors total) and four single wires to bullet connectors.
We are not talking about a complicated electronic device here.Last edited by boscoe99; 07-05-2016, 10:19 PM.Comment

That is weird, when I posted that, the diagram was not there, now it is. Thank you.
Now, can you tell me what each wire is for? ie. yellow wire = trim up, ect....
Sorry, I should have asked for that in the first place.

I have not a clue as to what brand or model of motor is in question.
Why do you need the diagram? Why do you need the functions of the wires?
Wire colors may be different on the motor, different on the harness from the motor to the tachometer and different from the wire colors on the tachometer.
With Yamaha it is all plug and play. Colors of the wires are not an issue.Comment

Ok, bear with me, trying to post pictures.Comment

Here is what I am trying to do and what I have to work with:
I have an older boat, 2001 Sport Cat, with even older motors, twin 1995 Yamaha 200's (L200TXRQ). The boat was extensively MacGyvered by the previous owner and I have been working on unfixing what he "fixed". Most notably, he removed the Oiler system and it is cost prohibitive to rebuild it, so now I just premix the oil and gas.
The old gauges were sun beaten to the point where I couldn't read the Tach's, so I replaced them with 6Y5-8350T-83's. I hooked up the Yellow, Green and Black wires. The blue has no corresponding lead on the engine side wiring harness, that I could find. The tach works but the trim does not (one bar flashing). The DIP switches are set as follows:
SW1 = Off
SW2 = Off
SW3 = On
So, my question is, do I absolutely need the wiring harness adapter, or can I jump the Pink wire from the Engine side harness to the pink wire in the tach four wire plug, to get the trim working?
I am attempting to upload pics from my Album....Comment

Verify your model number. An L200TXRQ is a 1992 model year motor. The connectors shown in your photos indicate the model to be 1994 or later.Originally posted by Joediveguy View Post
A 1994 through 2004 two stroke connected to a digital M/F tachometer would look like this.
I would simply buy the Yamaha harness to make the connection between the motor and the tachometer. You will then have the over temperature functionality and the trim functionality. But it is your boat and motor. If you want to string a single wire from the motor to the tachometer to get the trim information then you can do that.
The pink wire in the main engine ten pin harness is for activation of the warning buzzer. Not for the trim. The pink for the trim comes up from the trim/oil harness. Yamaha uses the same colour for two functions. Plus others.Last edited by boscoe99; 07-06-2016, 01:34 PM.Comment

OK, so it turns out both engines are not the same.
Engine #1 has a Data Plate, however, Engine #2 does not, it has worn off. I recall being able to read it when I got it a few years back when I was verifying the title., however, it is gone now.
The wiring harnesses are different for both motors. The original wiring harness picture I posted was for Engine # 2
I will post pictures of both engines shortly....Comment

Is there any other place on the engine that may have another data plate other than the transom bracket?Comment
