Grainger: If you want a "factory" lay-out for the temp guage, you will have to swap out the panel from the "D" model and run a different line to the sensor. You can't just add a NH guage to the existing panel-at least it doesn't appear that you can. I didn't push the dealer on this one since it is a lot more money (I suspect) than just adding the guage (which he did agree to do). If you want a guage inside the existing panel (rather than added to the cowling) there is enough room to mount a small one where the NH guage SHOULD be. You'll have to remove the panel so you can hole saw it without damaging the stuff behind the panel. The problem with that though is you might have crap from NH if something happened. If you simply add guages to the cowling (in circuits separate and apart from the existing NH systems) you shouldn't have any problem-i.e. they would be hard pressed to evade warranty work on that basis. Once the guages are mounted, if you want it "pretty" make (carve) a male mold (from rigid foam, clay or similar) to a form (lines) similar to the existing NH cowling, use that to made a female mold into which you can pour urethene (or similar), or, you could simply build up a cover for your guage(s) using fibreglass on top of a wood mold. In any event, something that small would be easy to do and the thing will end up looking (sort of) like it was designed that way. I havn't got my tractor yet, but I've looked at the shape of the cowling and I think the guages will be mounted flanking the NH panel. I am going to the dealer's tomorrow to take measurements and see how I am going to lay it out. The problem of putting guages across the top is that the NH cowling is pretty high and rounded and an additional cowl for the guages would raise it another several inches. Again, its not brain surgery. One of the nice "easy to work on" things about the NH is that access from the engine compartment thru the "firewall" to the panel area is very easy, easier than many other brands (the JD 990 is also pretty good in this area). Put your guage(s) where you think they will look ok. After all, it's YOUR tractor, not New Hollands. Take care. John.
