I went the Mazda route for the hitch and wiring harness. The hitch is mechanical mount only. Bolts to the frame. Mazda provides excellent instructions. When they tell you to remove the tape from the threaded holes for the bolts to mount to the frame, keep in mind that the forward two (one on each side ) were camouflaged with under coating. The hitch itself will not activate the Tow Mode. I am quite sure it is the wiring harness that does that. The hitch was 500 at the dealer and the harness was 200. That hitch was massive and well powder coated. Fit was perfect. Two side flanges are mounted first and must be only mounted loosely so that the main, center part of the hitch can be slid in between the two side flanges and then everything can be tightened up. Easy two man job. No need to elevate vehicle on jack stands.
Wiring harness is a bit more involved as inside trim on driver’s side, door sill and the whole panel that is tucked under the third row seat has to come away from inside of vehicle. Then the wiring harness, control module, plugs and cabling all straight forward at rear driver’s side back corner. Then you have to put it all back together.
We got it done. Good install. Requires three fuses to be installed . So I’m guessing it’s the harness that activates the Tow Mode.
The harness won’t screw up the Mazda nerve system. An aftermarket hitch would be OK.
But I wouldn’t trust the harness to anything other than Mazda,…. At this point.
