Works great. Customer service was above and boyond helpful. 100% excellent. Thanks for a great product!!!! 610937
I have not hooked up the unit yet. I have an overland osprey diesel pusher(dp). The coach has an exhaust brake. When the exhaust brake engages the brake lights automatically come on. Using a conventional electric brake controller like the Prodigy P2 would engage the trailer brakes when ever the exhaust brake engages, causing the trailer brakes to burn up on long down grades. I know this can be fixed by adding a diode in the wiring, but that involves tracing a lot of wires until I found the right one. this unit doesn't need to connect to the brake lights. it only needs the air pressure being applied to the brakes to engage the trailer brakes. It really is a sweet unit for a DP with air brakes. 682528
the information provided with the is stall is very veg they could have told you where to get a check valve they could have showed you in detail how and where to hook into the air valve , what lines to hook into , or offed a video on how to install for what it cost it is a rip off, you need to let hays know this for future sales 619342
Mike L - 04/09/2019Great Product. Fit like OEM 911137
Hard to adjust and you can't test the trailer brakes with it. Never fells like the trailer is getting power to activate the trailer brakes even though there's 12 volts going to the brake wire 875049
Definitely a great product! Easy installation and great instructions! I use my semi to pull my camper occasionally and this box works great for the electric brakes on the camper from the air brakes on my truck. 854653

Works great, shopping and customer service top notch 816865
Purchased this for a Class 8 truck with air brakes. It was easy to mount and to install. Wiring it up was a snap, but I was surprised that I ordered 2 and did not receive instructions with either. Had to go online to get a schematic and operating/mounting instructions. Wasn't a big deal as etrailer had it on the product description, but if you're old school like me you expect to receive instructions with the product. 796657
Works as expected Gives excellent braking proportion from air to electric. 787264
This is the best brake controller I have found. I purchased this to use with my International 4700 and disk brake set up. Smooth and reliable. Would most deifinitely purchase this again. 776990
