Search on ebay for Fox Remote.. I think there is one posted now. I set up both my front and rear with one of these levers and it is really trick. Fox RL rear shock and SID Black Box fork on the front.
For me, an novice bike mechanic, it was a fairly challenging task. But in the end I got it done and it's a unique and awesome upgrade. Let me know if you want more info.

PS there is a kit on ebay now, but it's in the UK.
