Hello All! Iím on my second Hopkins Insight Brake Controller. Loved the first one. Worked great but left it on the truck when I sold it. So bought another off Amazon (way cheaper than retailers) but with this one it applies the same braking force (which in my opinion is about 40% of maximum) no matter what gain setting I have it on or what percentage setting I set it at. At 99% and on setting 7 it barely grabs. My trailer brakes are auto adjustable and the brakes grabbed just fine with the older controller. Anyone else had this same issue with the Insight brake controller?
Sounds like it's defective. I'd return it for a replacement or your money back if it were me.
I was thinking the same. I put an email into Hopkins but it’s the weekend. We’re on a trip at Lake Seminole as we speak. Luckily South Georgia is flat and rural. I just went to a local AutoZone where they had an Insight Controller but wanted $149! I got mine on Amazon for a third of that. And they’re listed for even less now at $45! I’ll wait till I get back home and order it.
Think I figured it out. I had an 02 Suburban before I bought this 06. In the 02 the red wire on the Hopkins brake controller adapter went in slot A. So I assumed the same for the 06. But it didn’t work properly when I first hooked up the brake controller to the 06. I called Hopkins support and they said 03-07 GM models the red wire needed to go into slot D on the adapter. So I changed it. Hopkins says by putting the red wire into slot A the first time it probably damaged the unit. They’re sending a new one at no cost. Very nice people.
