Some hitches are just too easy to install yourself, I put one on our Vibe in about 10 minutes. However for our Subaru it took a fair bit or mucking about to get it on right. Same with wiring, sometimes the module basically plugs in, sometimes you have to splice and solder.
So, figure out if it's plug and play and you can do it yourself, if not, I'm not sure where to go in Ottawa.
