Newbie R-Pod R-178 - Event Date: 16 Mar 2021

+1 to stephenH’s suggestion to check out the videos on Etrailer. They also have install kits for various vehicles you can get which make life easier.

The 4 wires to the controller are battery +12V (which needs to have a second circuit breaker, 20A is fine), ground, output to the 7 way for the trailer, and a stop light connection (so the controller knows when you use the Tundras brakes). That and the color codes should all be documented on the install sheet for the controller. On Tekonsha controllers the coding is blk +12V , wht gnd, blu output, red stop lights. That should be standard for all of them but no guarantees, check the instructions.

Ok, I am going to run 2 wires power and brake using 10 gauge wire. My new question is what 4 wires plug into the controller under the dash?

Thanks, I was wondering what the power lead was for. Apparently my truck was not wired for the 7 wire plug. The hitch is there and a 4 wire plug. The bracket is located but there are no wires for the 7 way plug. 

Thank you so much for the offer. I have purchased the adapter but I can not locate the plug under the dash. I purchased the truck used and it has the heavy duty hitch bolted to the frame and a 4 way wired under the frame. There is a bracket for the 7 way plug. 

Thanks, my wife and I are excited to take a trip on the Natchez Trace soon. We had a 35’ trailer in the 80’s, but we had a 3/4 ton van to haul it. That was for work, the R Pod is for pleasure. We are both retired so we have to use what we have, the Tundra. I am confident it will do good.
