for those wondering how to connect to DTP connectors on roof

[reidanerg]

so I went through a lot of trial and error, so hopefully this makes life easier for everyone else. To connect a light bar to the roof AUX DTP connectors, all you need is the contacts for the male plug thats provided. (I thought it was a dummy plug but it isnt, it's functional and just needs the contacts installed) It seems super obvious to me now, but I didnt find any info while searching.

Bad design that there is no roof rack power on the passenger front side - they should have run a four pin dtp there so you could plug in a scene light and/or a led bar…

couldn't you add a 2 way splitter?

It is not always easy to find stuff with the forum search function. One reason I started the lists.

Yes absolutely - but it takes up a lot of space - you're now trying to squeeze 3 plug/socket pairs into a space where only 1 is required if the design was sensible. A 4-pin female would support both the roofrack scene light power AND the roof bar power simultaneously.
