Question:
I am trying to install a REDARC Tow-Pro Elite into a 2018 Toyota Tundra Platinum. It appears the Tekonsha wire adapter is only good for up to 2017 for the Tundra. Is there a plug in wire adaptor for this application and if not how do I splice in to the Toyota factory wire harness? Attached are two pictures of the plug that connects to the back of the factory brake controller. Thanks for your time

Expert Reply:
At this time there is not a wiring harness compatible with the 2018 Toyota Tundra models from any of our manufacturers. You will either need to use a circuit tester like # PTW2993 to confirm the pin functions on that harness you pictured and splice into it or you will need to hardwire your 7-way to your Tow-Pro brake controller using # 5506 or # ETBC7.
I've attached a couple articles to assist.
