Be careful with which switch you select. Ford made at least six variants of this switch, and they all look the same, as the one shown. They will accept the plug from Gen 2 Viper and snap in the instrument panel, but they will not work properly. You need to find the switch that has all 15 pins populated, a center barrel bulb installed with the proper contacts and ONE pull out detent for fog lights, to use in a Gen 2 Viper (for purposes of research on this post we are talking about '96-'02 GTSs and '97-'02 RT/10s--'96 RT/10s used the old Mopar Gen 1 switch).
Although the switch pictured looks physically the same as what is in our cars, the switch pictured is not correct for Gen 2 Vipers. The switch pictured, at a minimum, will not provide knob illumination. If it were correct, it would show a bulb pre-installed in the center barrel. Depending on the variant, it MAY also not activate the fog lights, as it may not have the single detent pull-out feature. (Also, Mopar-supplied switches would have a black foam cover on the face so you don't see the orange body with the Ford logo when you install it in your Viper instrument panel, but that does not affect operation, of course. That was only present on switches installed as a Mopar part. You would not find it on a switch installed in a FoMoCo vehicle, or a Motorcraft service part.)
Interestingly, this switch family from Ford has at least the following variants, depending on how the switch is configured internally, and they all look the same: 1) Standard Off-park-on clockwise twist with knob illumination from the side in a separate housing; 2) that switch with knob illumination inside the center barrel; 3) a variant that had clockwise off-park-on with ONE pull out detent for fog lights and side knob illumination in a separate housing; 4) that switch with those features and center barrel knob illumination; 5) clockwise off-park-on with side knob illumination and TWO pull out detents for European rear bad weather lighting; 6) that switch with center barrel illumination. There may be more I have not found yet! (I vaguely recall a variant that had one counterclockwise activation position for something, but I can't recall for sure. It was on a European market vehicle, if memory serves.)
The variants of this switch were supplied with light tan, medium green, light orange and dark orange outer housings across all its Motorcraft applications/part numbers. It's an interesting switch in how it was configured internally to install in a number of North American and European applications. At the plug end, it was supplied with (at least) configurations of ten pins, twelve pins, 13 pins and 15 pins populated. The remaining pin locations were left empty. Because of how the switch is configured internally, you have to get the exact switch for it to function properly in our cars. At a minimum, the wrong switch will leave you without everything working properly; worst case scenario is that it will pop a fuse, or fusible link, if you install the wrong one and activate it. As far as I can tell the lone correct version we need has an "-HA" suffix (rather than "J" on this part number shown in the above original post), molded into the outer housing. That has the 15 pins configured correctly, has one pull out detent for our front fog lights, and has the contacts and the bulb installed for knob illumination.
The Mopar part number is 04763135.
Hope that helps if it prevents someone from buying the wrong part.

Thank you for the very illuminating background! (Pun intended)
As with many electrical parts, just because it looks the same and fits the hole and plug, doesn't guarantee full and proper operation. Perhaps most variants of the Ford part could be used in a pinch to get a Viper safely down the road at night.

It is an interesting switch design, and it would all be done through one switch assembly, or maybe a touchscreen, and some software now!

If it came out of that Mopar box, that is the correct part number, and looks like it would be the correct switch!! The picture of the Ford part does not show a center bulb, so it would not illuminate the knob, and is not correct.
