I have heard that the back-up lights may not be necessary. Search for a thread about this subject within the last 6 months or so. There was also an issue with daytime running lights, also probably not required in Canada. It might depend where in Canada you are though...PM me for any other info you need...
I made the wiring diagrams for all 3 versions of the car...You'll see many posts about them in this forum....Examples are in my gallery...
Depending on your transmission, the reverse switch is already in place. What you need is a light, power source, fuse and a ground. I have seen the switch wired both + and - depending on your preferences.
