Hi all,

I need to wire my 2015 Caravan for a brake controller and 7 pin connector. I would like to run the power wire for the 12V power feed through a relay triggered when the key is on as opposed to directly to the battery. I'm looking for a suitable circuit that I can splice into under the hood to trigger the relay but can't seem to find any wiring diagrams for a 2015. Any suggestions?

Also if anyone knows of a source for a 2015 wiring diagram that doesn't cost hundred's of $'s please let me know.


Thanks,
Rob
