Cargo bed lighting

[george154302]

I can see there has been a lot of discussion on here about cargo lighting, I recently installed a cap and I want to install the factory cargo lights and also lights on the inside roof of the cap. Did some investigating on wiring under the bed and the only caped plug I found is on the end of the left frame rail, looks lik it has the tan and white wire in it, does any one here have the wire diagram for this plug and what the wires are for, 2018 Laramie, would be greatly appreciated

Pretty sure that's the one but cannot swear to it. I have a 2014.
WOudl love ot have the OEM Bed LIghts you guy can get.
ALl the light, from above, sometimes ain;t enough.

Been thinking of going with long stick up strips to help out.
