How to install a Tiny Tach into Glovebox
This is to all who was asking on here they wanted more in depth instructions on how to install a Tiny Tach flush mount.
97 thru 99 GP1200
1. Take glove box door off by unscrewing the nuts from the hinge.
2. Place the commercial tach on the inside of the door/or outside and outline the tach with a marker.
3. Take a small drill bit and drill out each corner(marked with red dot) on the inside of the marked box.(pic 1)
4. Take a Dremel/w a cutting wheel and cut out the box on the inside of the line(marked in blue).(pic1)
5. If the tach doesn't fit use a file and file the sides down CAREFULLY not to overdo it.
6. Now when it fits I file an angle on the outside of the box to make it look better.(pic2 & Pic3)
7. Mark the holes for the nuts and screws to hold the tach on. I also used lockwashers.(pic4, Pic5, & Pic6)
8. Run the wire through the drain hole in the box(dont forget to use a rubber gromit).(Pic7)
9. Now you can run it between the seat and hull or drill a hole with another gromit above the seat in the hull(this is what i did).
10. Finnally wrap the red cord around the sparkplug and round the white one(this was just a temp spot for me).(Pic
Notes: Remember to silicone all the seam lines in the tiny tach and around the wire where it goes into the tach. Then i put a bead of silicone around the hole i cut into the glove box. Also I am going to counter sink the screw holes and use red painted Screws so they match and are flush. I also left the sticker on till the end so i wouldn't scratch anthing but i advise not doing this. The sticker is really hard to get off. So take it off first.

I find the commercial tach to be ok for people who are an everyday skier that just wants to have knowledge of their rpms and where they are sitting. I have found also that the commercial tach has been proven to be the most water resistant along with using silicone on the seems. I do suggest getting the PET2100 if you are fine tuning and on the edge of being lean/rich and always trying to push a little more. But like i said if your an everyday skier and running a little safe(on the richer side) then a commercial tach is good. IMO I would NEVER get the regular tiny tach. The reasons are that it is very slow in updating, not programmable, and does not have the top rpm readout.
