Review on CARROFIX Vehicle Side T Connector Trailer Extension by Zach Clements

I needed more light for back up at night. I got this because I didn't want to press the factory 7 pin gladiator harness. There's a good reason they don't include a wire color code legend. Different trucks use different colors and occupy different positions. In my case, red is a backup. The rest of the wires are pretty consistent. Also, they don't expect people to need to know which contact is which. As the main function of this wire harness is to separate 4 pins. And they really accelerate. Otherwise good workmanship, all plugs are protected by shrink tubing. In this case, the shrink tubing on the 4-pin side of the connector will expand. They had to use heat shrink tubing with glue to keep it from slipping.
