I checked out Amazon Australia and found a CX3 towbar for "only $756.43", and a Genuine Mazda Towbar Wiring Harness Kit for only $199.61 but hey! FREE Delivery
I've never seen a Fuse Tape before, those solve a big problem, thanks.
Being my wife's "new" car I might just go ahead and pay for a pro install. I can get home install for less than the Australian Amazon hitch.
I enjoyed the videos. I don't know much about modern car construction so they were enlightening.
