Is Reprogramming Required To Install A 2019 Volvo XC90s Wiring Harness

Question:

I just installed a hitch on my 2019 Volvo XC90 and now putting in the Tekonsha T-One wiring harness. Am I going to need to take this to the dealer to reprogram before install?

When installing the T-One Wiring Harness # 118683 on your 2019 Volvo XC90 there will be no need to reprogram. To help in your process, I've included an installation video for a on a '18 XC90. The video will show that the 4-way connector works without reprogramming.

Should you decide to do some towing a great Ball Mount Kit is part # 989900. It comes with two ball mounts - one with a 3/4” rise or 2” drop and the other with a 2-3/4” rise or 4” drop - a 1-7/8” hitch ball, a 2” hitch ball, and a pin and clip to cover all your bases.

You can use the link to the help article on ball mounts I've added to determine if this kit will give you the correct amount of drop or rise. I've also attached a link for selecting hitch mounted bike racks as well should you be in the market there as well.
