I used this unit and have a spare which I am still thinking of using in my 09 camry. I have installed 4-5 of them and they are quite simple, I do not use the connectors, and direct wire with tape and heat shrink tubing.

I you want the factory "Canadian" look which I do not like due to the high power consumption the here is a link for the module

as for the led bulbs try here I have done several of these mods

Like I mentioned before if you use the web electric module for about 40 bucks or 50 shipped to Canada, then change the turn signal bulbs to led you will save gas by reducing electric consumption and reduce or completely eliminate any heat build up which may or may not distort the turn signal lens.
here is the specific cross referenced bulb for the turn signal 3457 which convert to 3157 or 3157/a, they are 3 watts each which is far brighter then the standard lights in the camry
