*Update: So I wasn't able to complete the undersuit in time for Halloween. But I decided to get a Tron costume put together regardless. I was in a mad rush to get this done as I procrastinated until the final hrs. Here are the results after 10hrs of labor.
I'll still be continuing this project until I reach perfection, or at least a replica suit that is satisfactory in my eyes. And I have pretty high standards for this project!
I used actordiver's technique of overlaying electrical tape over the EL tape.

(thanks for the inspiration!) Here are the strips I used for the legs:
I laid out each strip on my motorcycle jacket and a pair of leather pants. I didn't want to modify the jacket permanently as I actually use it when I go out riding, so this was another reason for the electrical tape.
My Sidi vertigo air boots came in handy as well. Again, just a temporary solution so I covered all of the emblems and logos in electrical tape.
I used these clamps to connect the wires to each piece. They worked like a charm and held up all night! No soldering, gluing, taping or drilling required.
All ready to be taped down and wired up!
