Holy crap, had to dig back through the pm's to find this one! haha....here is his post that he sent me, it was Adrenaline Revolution on here, I'd talk to him if you have any issues. I was going to do it, just never got around to it.
and for some reason, his website wasn't valid, so I added another parts fiche, they SHOULD be the same, although I'm not positive!
Go to a DOO Microfiche like this one...
http://216.37.204.206/xtremepowersports/Skidoo_OEM/Skidoo.asp
select "SKI DOO" and "SKI DOO" (again)from the drop down menus.
then select 1999
then select "Formula"
then select Formula Deluxe 500 LC/583/670
then select "02 fuel system"
Look at about the center of that page.
You need parts...

Remove the throttle cable, remove your grip, then you pull your old trigger assy and trigger mount off your handlebars, slide out the kill switch.
I had to cut the plug off of the new thumb heater and cut the wires from your old thumb heater near the plug (Unless you know how to remove the connectors out from inside the old plug and replace them with the ones out of the new plug)
then just splice them color for color.
slide the new assy back on the bars and slide your old kill swich back in.
reinstall your grip, Re-install the throttle cable and your done.
It's really a pretty easy job and you probably already know how to do all the steps but now you know where to find them!
They were all in stock at a local DOO dealer.
I think I have a pac of it and will try to post it on the thread where you saw this.
Good luck!
