7 circuit aux. fuse block

[RayB]

where do I get a key hot wire for the relay, I used a jumper in the fuse box on my 03. Is there a jumper that will work or the 2014

I used the cigar lighter in the center console. Instructions are one here about how to get to it or you can check out Transfer Flows website. I used it for the keyed on hot wire and made the splice in the center console to keep it clean and dry. Ken Irwin

Hi Ray, I can't answer from experience because my truck hasn't arrived yet, but:
you may know about it already but the Ram Body Builder's Guide contains lots of extremely helpful and detailed info. Here's a page (from the 2014 truck) on your query: http://www.rambodybuilder.com/2014/docs/ram/ramhduhbc.pdf.
(Note if you're on a Mac or Apple handheld that site doesn't always work properly.)
Also for more general wiring info there is this site: https://www.techauthority.com/en-US/Pages/Home.aspx. Many, many menus once you've selected your truck configuration, showing each individual circuit, connector locations, etc etc. A lifetime of reading while I wait for my truck!

(On edit: Changed TechAuthority link to home page because the link I had posted was a timed out session.)
