Camper shell/3rd brake light (HMB)

[Musky Mike]

I'm putting a camper shell on my 2019, I looked behind the left, right and under the spare tire (up in the frame area) for the 3rd brake light pig tail and didn't see. Does anyone know where it is at?

Taped to the frame on the driver's side about at the spare tire. It's a white and purple wire on a 1500. You may have to move the spare but it's usually visible. Keep looking.

I took the harness apart, there is no white and purple wire in it. Over on the drivers side (the hub of harnesses going up to the tail light) I took that harness apart, no white and purple wire.

If your Leer cap has the hub in for the brake light and dome light, you can order the Leer 7 way harness kit number 300100 (2010-to present Ram truck). It Ts into the back of your 7 way trailer plug. It's 100% plug and play, it comes with 3 different end connectors to match the hub in your Leer cap. It took me about 30 minutes to install.
