Ducati Monster Forum

Hello,

I did an engine swap on a 1999 M750 a while back; now the bike has a 900 engine in it.

The wiring and harness & other electrical stuff is unchanged.  What I want to do is change out the old 750 gauges (no tach) and replace with the gauges/dashboard from a 2001 M900.

There is a new one on ebay, the entire unit new for $240.00.

Does anyone know if the 2001 dashboard/guage cluster will 'plug-in' to the wiring on a 1999 750?

Thanks for any ideas you can offer  :)

Any of these should work, 2001 had EFI and Immobilizer . . .

I put an M900ie cluster (minus the tacho) on my '98 M750.

You'll end up lacking one idiot light, *if* you can get the tacho to work.
I suspect the 900ie tacho works on a "pulse signal once per rev", and that may be a problem.

I used an SPA tacho, so I'm lacking two idiot lights.
The neutral wiring is fubared somewhere in the harness, so that light got swapped to oil pressure.
I don't have the sidestand switch.
So I've got high beam, turn signal, low fuel, and oil pressure (on the neutral light).


IIRC, the plugs are the same, but you'll need to juggle the wiring around a bit to get the right idiot lights.
I don't remember exactly what I had to do.
There were some broken wires in the bits I was putting together, and added wiring for the SPA tacho, so it was a bit of a fiasco.

No immobilizer until '02

UPS!!!! didn't notice I re-typed '01 . . . must be age . . .

Carbed bikes have a different tacho signal than the efi bikes.  Other than that and the wiring issues above, it ought to work.

hey thanks everyone for the responses.   Looks like i have a bit of mucking around to do to make this work....maybe i'll keep looking for a dashboard off a '99 900.

unfortunately, just purchasing a tachometer will not solve the problem, as the 99 750 didn't have a tach & the original dashboard is still on the bike.  i need the whole unit that was meant for a 900 with a cable driven tachometer: dashboard, both gauges & idiot lights.

i appreciate the suggestions  :)

hmmm....i also just realized that the front tire on a 750 is different size than 900, so the speedo will be wrong.

i think i may just purchase a friggin' tach by itself and figure out a way to mount it up front.

Waitaminit.

What year 900 motor is it?

The horizontal head has the tacho drive on it?

FWIW, the speedo is gonna be wrong no matter what.  :P

'99 M750 .  . so says the tittle . . .

speedo drive is different, speedo is the same for the tyre size.

ss carby motors have a cable tacho drive.

What year 900 dash did you use?

I bought the same one 2001 dash the OP is looking at for my carbed 900 build, based on the results of this research;

Part numbers for the wiring harness AND speedometer are the SAME. So I can't think of *any* reason why the idiot lights wouldn't all work. The speedo is mechanical, so that was that. I figured at worst case scenario I'd need to swap out the tach and I'd be fine. I didn't even think that should be necessary, since it's a mechanical tach.

Still sitting in it's box waiting for me to build my bike though, so that's all theory. :)

This one should work also:

I'd like to see pics of the front and back of this 2001 M900 gauge cluster.

Cable drive speedo and tacho is what you're saying, yes?

Yep, or so I thought;

Front:

Back:

The part numbers that are identical between the '01 M750 and '01 M900 are the following: speedometer, wiring pigtail. Basically the tach is the only thing whose numbers don't jive. The backside looks identical to my M750 dash, here's a photo for reference of the M750 backside:

The actual bodies/cases share the same part #'s as well. Both tachometer's are actually described as "electronic tachometer" in the parts diagram, which I assume means they get their signal from the coils. The only "mechanical" tachometer output I can think of is on the front side of early carbed 900ss engines, above and to the right of the horizontal head timing gear.

That cluster is for an '01 Monster S4.

Good to know. All this time I assumed it was what the seller said it was.

Are you proving me wrong about something? I'm not following.  :)

I hope it still works for it's intended purpose, now I'm concerned.  :-\

No, not proving you wrong, just identifying what part you have.

If your existing 750 tacho has the same style face, swap it in, and check/swap idiot light wires as necessary.

You can use the water temp light (bottom center) for whatever.

That's what I'm thinking...I just emailed the seller. He seemed annoyed that I ignored the huge words; KEY CODE. But the part # from that listing doesn't even line up with an S4 of that vintage. I'm pretty sure I can get this to work without too much hassle, Mainly I'm concerned about the wiring pigtail now. It only has 3 simple jobs to do, and obviously no ECU means whatever immobilzer may be in there is of no consequence to me. Worse case scenario I swap my old pigtail in.
