The Retrofit Source filters reviews on their product pages, so beware that you'll only see the positive ones show, not a single negative one.

Just like this other customer, I wrote a fair and honest (but negative) review of a product to inform other customers, and they simply did not publish the review. So they have forced me to post here where they aren't filtered.

The Morimoto Motocontrol harnesses use cheap connectors with gaskets that are not properly sized to the ga of wire, so they have big gaping holes for moisture to enter, and cause corrosion. I've had two sets of these harnesses fail on me now, and both times I lost my headlights entirely. Super super dangerous, and extremely lucky I had a full wiring kit with me, so I could custom hardwire the ballasts straight to the battery to regain my low beams for the ~2hr drive back into reception. If I didn't have this with me, it'd have been an overnight on the side of a winter road in -25C... and major lawsuit territory if the failure had caused an accident.

The worst part? This is a well known failure point, and hasn't been corrected for over 4 years now. When asked, TRS denies this being an issue at all, and this was the reply: (unacceptable reasoning, just fix the damn issue like any reputable manufacturer would have done within a few months)

"There are no plans to change or redesign the wiring harness at this point, so any that you order will continue to be exactly the same."

"Aside from filling all the open/exposed electrical contacts with dielectric grease to further keep water out, there's not much else that can be suggested."

Photos: First two are a brand new harness in Oct 2018 showing the gaping holes in the gaskets, the other photos are of the corrosion on the contacts that this flaw allows to occur with moisture sitting in the connectors.
