Yeppers, isolate the battery, and touch the CABLES together. That discharges the system. You MAY see a tiny spark, prolly not, but if you do don't be concerned. Yank the fuse for insurance.

Crazy Pete had some pointers too, mark the splines on the steering wheel, and shaft. No guess work that way. Although I'm opposed to smaking my dashboard (She's faaaaaast, but she's a show car too! LOL) checking the HL switch first is faster and easier than the column switch.
