Question:

I recently bought a 2018 Tundra and I’m needing to install a brake controller for pulling my camper. I bought the primus IQ controller but I’m having trouble hooking it up. No one can tell me where the plug is in the dash for hook up. Any help would be appreciated. Thanks,

To install the Primus IQ # TK90160 on your 2018 Toyota Tundra you will need the plug-in adapter # 3031-P. If you take a look at the attached photo from the installation instructions you can see that the connection that the plug-in adapter connects to is located behind the access panel to the right of the steering column. It looks like you are looking at the left side under your driver's side dash (which is where it is located on most vehicles) which is for the Tacoma.

A sample installation video has been linked of this same adapter being installed with the Prodigy P2 # 90885 on a 2015 Tundra that you can use as a reference.
