Why Is My Tekonsha Primus IQ TK90160 Showing An o9 Error When Plugged Into A 2016 Ford Flex
Question:
Just installed Primus IQ in a 2016 Ford Flex with Factory tow package. Used a plug and play harness Tekonsha 3034-P Our issue becomes apparent when using the manual slide button - it can get to 5 or so, maybe even 6, and then shows the O9 ground connection error. What is happening?

Expert Reply:
The o.9 on your Tekonsha Prims IQ # TK90160 does mean you have a bad ground connection. This will be due to the # 3034-P plug that you are using.
As your 2016 Flex came with the factory tow package, you will actually need the # 22292 plug. The vehicle end plug will look the same on both these pigtails, but they will be pinned differently. With that being said, you have one of two options to fix this.
You can return the # 3034-P and purchase a new # 22292, or you can re-pin the # 3034-P. I included a picture of both vehicle ends as well as how the # 22292 is pinned for you to check out. The picture of how it is pinned is looking at the wiring end at the back of the plug where you can see the numbers for each port. This is actually pretty easy to do and will be my recommendation.
