The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…

For your 2017 Mazda CX-5 we have two trailer wiring harnesses available. The Curt part #C56377 and the Tekonsha part #118746 which you mentioned. In general the Tekonsha kits are more reliable and less likely to short out. Partially due to the fact…
