Exact fit and best price.
After watching a"How to video clip" on A1 auto website on replacing this part I purchase it. It was easy to install, after I learned how, and was the best price of any of the auto parts stores.

Saved Money with Easy to Install Part
The installation video for the part was clear and concise. It took about 15 min total to install the resistor. The price was about a third of the dealer's price. Shipping to Canada is about $40 but still worth it to save about $100. Estimated delivery time was accurate.
