Question:

Hi. I have a 2015 rv on a Freightliner frame. What do I need to install? Do they have a plug under the dash?

Expert Reply:

There are several different Freightliner chassis types used for RVs, such as the popular XC-series that is often used for Class A diesel motorhomes. This chassis can allow for plug-and-play installation of a trailer brake controller such as the Tekonsha Primus IQ Trailer Brake Controller # TK90160 so long as the RV has a factory tow package.

In this case you will use wiring adapter part # 3027-P to connect the Primus to the under-dash port. This adapter also fits 2004 - 2015 Freightliner SL Series chassis with Factory Tow Package.

If you do not have the tow package you can still install the Primus IQ using our hardwire install kit # ETBC7 along with a 4-pole harness. You may also need additional 10-gauge wire # 10-2-1 and butt connectors like # DW05745-10 to reach the 7-way at the rear of your motorhome.
