Do you know how to use a solder iron? I think that's the best way to hook wires up to whatever you need. But you need to know where to hook the wires up, and most importantly which end is the positive terminal and which end is the negative terminal.
The LED assembly is going to take some fairly intricate work. There is a certain pin-out that has to be followed to get it to light up, and even then you need a transmission device of some sort to even have the LCD display anything other then all 000000 or -------.
You may be able to hook up a 4017 decade counter that would make it work somewhat similar to a Boba Fett chest display.
Scur Falco is our electronics expert in Mercs, and when I say expert...I mean it. He has put together a ton of vids on making electronics for your own chest displays, thermal detonators, ect. If you tell him what you have and what you want to do with it...he'll be able to help you.
thanks guys,
