All you need:
Digital voltage meter.
Philips head screw driver.
and from the looks of it, that black valve cover cover thingy with the 24V stuff has to come off... so you'll need a socket wrench for that (If I remember correctly).
and to make the job easier, get a pair of either safety pins or streight pins.
As long as you have those tools, it takes about 5 minutes tops.
