They're pretty easy to change. A 10mm socket and something to turn it with, the underseat torx drive to remove the body work, and some snips to cut the zip ties with. It's defiantly an easy parking lot job if you have to do it, but having a garage and some beer handy sure is nice
I had mine replaced in about an hour or two all said and done. You do have to solder some wires together on the Rick's unit though it doesn't come with the connector so you have to cut your old connector off and go from there. The instructions say NOT to use crimp connectors. Not sure why guess the possibility of them coming loose that way.
The longest part of the job to me was soldering the connector cause I suck at soldering. Probably should have just said screw it and used good 3M connectors instead but oh well.
We'll see how long the Rick's unit lasts. Hopefully as long as my stock unit.
