Excellent review for engineering design,
Excellent review for engineering design, materials, fit and ease of installation.
I would suggest one improvement to the electrical harness extension cable. Redesign the extension cable to the proper connector to mate and lock on both ends, not just one as currently designed. I created a "lock" on the cable end without this feature by using two four inch nylon cable ties. I also installed two stainless rubber cushion clamps. One on a nearby aluminum tube and the second on the wiring harness extension. By fastening these two clamps together, I was able to secure and route the wiring harness extension cable to a secure location.
Lastly, I reutilized the OEM hose clamps (4). This allowed for a very clean installation.
