Sorry if this question has been asked before. I've searched and keep coming up with other models. I have an '04 r53 cooper s. I bought a receiver from out motoring not thinking that I'd need wiring too. Where I live if you can see the vehicles lights you're cool. I'm planning on using a uhaul cargo trailer from time to time and don't think the minis lights will be visible. What wiring harness can I use that doesn't cost $85? I've found a Hopkins one on amazon, 46255, that I believe will work. Has anyone used a brand that didn't come directly from a mini dealer?

Thanks for any help I can get!
