will look similar to these on my Boler
. If you read the captions under the photos I believe I documented the approximate pricing.
Check out etrailer.com for a brake controller for your vehicle. The P3 would be a good choice. Price was 1/2 of what I could get it for here in Calgary Sometimes they will have a $5 shipping special to Canada so go through their checkout system. The current shipping costs will be displayed on the last page before you have to submit payment.
They also have a lot of informational videos. Some of which are vehicle specific.
Depending on your vehicle you may be able to get a wiring harness that plugs directly into your existing wiring. Otherwise you will have to tap into your wiring as I demonstrate in my photos for my Sonoma tow vehicle.
If you have a Princess Auto near Stouffville (I think there is one in Newmarket) they will generally have the brake components if your trailer does not already have them.
My approximate costs were ($Canadian)
Brake Hubs and Drums $240
Breakaway Switch $25
Brake Controller $150
Wire and Misc. $50
