If you get the update kit, rather than the stock plug and play, get the crimping tool. Yeah, it's a bit spendy, but well worth it for the quality of the crimps.
Also, visit Eastwood and get their zip tie gun. It is invaluable for all the small ties you will use. You can set the pressure for how tight they get and then it cuts them off CLEAN, not with the invisible razor blade on the end...
