Question

Question:

I want to install a electronic brake controller on a 2020 Mercedes Benz GLS-450. Per your site looks like it would require splicing of wires. Do you know of company in the Baltimore-Washington DC area who could do this work

If your 2020 Mercedes Benz GLS has the factory 7-way you can easily install the Redarc Tow Pro Elite part # RED44FR with just the install harness part # 3066-P. If you do not have a 7-way you'd have to install a 4-way like part # 119250KIT with the 7-way adapter # ETBC7 so that you could install a wireless brake controller like the Curt Echo Mobile # C51180.

To find someone to do the install best option is to find a local mechanic to you with a good reputation and let them tackle the job as this type of install is very basic compared to what they normally do.
