Which Tekonsha Primus Brake Controller will Work with 2016 Ram 1500

Question:
Hi, I have the Primus 90155 proportional controller. The description for part 3016 wiring/plug indicates its compatible with many different Tekonsha controllers, including the Tekonsha Primus IQ TK90160 , but it doesnt list my 90155. Looks like the same plug, just double-checking it will fit. Target vehicle is 2016 Ram 1500, but Im mostly concerned about the brake controller end of this cable, not the vehicle end. Thank you!

The Primus IQ part # TK90160 is the updated version of the Primus 90155 that you have. Your version of the Primus will not work with your 2016 Ram 1500 because the new Rams use a multiplex style of brake light wiring that your controller won't understand. It will think that the brakes are on all the time or won't work at all. So the # 3016 will technically plug in to your controller but it won't work with your truck. You'd need to upgrade to the new version of the Primus with part # TK90160.
