Wiring Adapter for Primus IQ Brake Controller in 2019 Chevy Silverado 1500 With Factory Tow Package

Question:

Primus IQ installed with GM harness and it will not work. No lights on break controller. 2019 Silverado with trailer package came with the pigtail for truck soldered harness together and plugged in and will not light up. Harness for trailer seems to be good connection. Fuse in main fuse box under hood has fuse in #84 listed as trailer brake fuse. Trailer lights up when plugged in.

It sounds like the issue is that you are not using the needed wiring adapter; though I was unable to locate your order number to find out if you also purchased the adapter when you purchased the Primus IQ from us.

To use the Tekonsha Primus IQ Trailer Brake Controller # TK90160 with your 2019 Chevy Silverado 1500 that has the factory tow package you will need the Plug-In Wiring Adapter for Electric Brake Controllers # 3064-P in order for it to get power. I have added a link to a video review of this adapter for you to check out as well.
