While I can't help you specifically with a wiring diagram, I can make a few suggestions:
A) This area is for new members to introduce themselves. You'd be better off asking questions about your vehicle in the section that is specific to your vehicle (truck, suv, sedans, etc...). Here is a direct link to the 'Ram' area:
https://dodgeforum.com/forum/dodge-ram-20/
B) If you hear the relay click, that means it is getting a signal from the ignition switch. It doesn't mean that it is passing power along to the fuel pump. From what I remember, Dodge used to use a 'shut down' relay. It would power the ignition and the fuel pump. Anyway, check for power in from the switching leg of the relay.
C) I don't have a fuse box diagram, but you should have one in your owners manual. If you can't find that, there should be a diagram inside the fuse box or inside the fuse box cover.
Good luck with your truck. The only other thing I'd suggest is that you ask questions and do diagnostics BEFORE buying any more parts. It gets really expensive, really quick if you just buy parts and install them without checking to see that the original part is bad first.
Welcome to the Forums, you came to the right place.
