Hey guys, I plan on making a passthrough and was wondering if i decide to use a LED, if i'll need a resistor next to it? Thats all.
Thanks!

Yep, unless you use an led with an internal resistor built in, like some of the radio shack ones.
Probably not... It's radio shack... Lol
They have a few rated at 5v that will work without a resistor...
This will work... 5mm Blue LED - RadioShack.com
Just cuz an LED has a forward voltage of 5V does not mean you can run it naked on a mod. For one thing it will be way too bright. And the resistor does more than just limit volts it also limits the current, these things usually want about 30mA tops.
I hear ya Willy, but that particular led worked fine on a few mods I have built without a current limiting resistor, which is why I suggested it. Theory is great, but in this case practical experience is speaking.
After i solder the wires to the battery connector, are there any issues with covering the soldered areas with jb weld to strengthen the connections?
Well, it becomes unrepairable, that seems to be an issue. I've never used JB weld to strengthen my soldering connections, and you shouldn't need to either. Just solder correctly and you'll be good to go.
I was also thinking about it just for protection from any juice that may make its way in there
I actually skipped the led, wanted to get one that worked first, the next one might have a color changer in it
I usually use hot glue for that because it is easy to remove when I need to do a repair and it has a relatively high heat capacity.
