I have a question about the calibration process. Technical support was excellent with a response in less than 24 hours.

The wiring harness I ordered had to be modified with the wiring harness from my Toyota 4Runner. This brake control works very well with my electric brake caravan.

Please note that the cable to connect to the car is not included. You need to buy a separate belt. The inputs (and outputs) are in a socket on the unit, there's no way to connect them unless you buy a wiring harness. I bought Redarc universal suspension as I had an old car. The only cable in the kit connects the box to the control knob on the dashboard. Easy enough to install for someone with some knowledge of car wiring. It is good that it is hidden and there is only one control button on the…
