Hello Luke,
As stated in my review response email, as well as in the Support Team's response to you. The wiring harness shown in your photos is the harness that is included with this brake light, and there is no need to strip any wires.
The installation requires adding the connections using the supplied vampire clamps, as outlined in the instructions on the product listing. We apologize for any confusion caused by the previous review response from 2023. The 3 year old review has not been removed but has been updated to avoid any further confusion. Please remember that some products are updated throughout the years, and some review responses may be out of date. If you ever have specific questions about products, we suggest reaching out to our support team prior to purchasing or installing.
As our team offered in their response, if you would prefer not to install this brake light, you are more than welcome to return it to us for a full refund. Please let our team know.
Regards,
