| Just take your time and make sure you're looking at the correct wiring diagram - the instructions are a little tough to follow (if you've had too many beers) and branch off to several different models. I used a fish tape to pull a string thru the bars and then pulled the wiring harness back thru.
Give yourself a couple of hours for the whole job.
You may want to test them before you install them - several people on the Yahoo TC88 group are complaining about dead left-hand grips (supposedly the MoCo has extended the warranty on that side - keep yr receipts).
