Replaced fuel line and added electric fuel pump, now won't start.

I finally broke down and ordered a new fuel line because it's the only part of the fuel system that we haven't replaced. Decided to ditch the mechanical fuel pump too for an electric. Anyway, some time during the process, I unhooked a jumper wire that fed into a plug. I assumed it was something to do with bypassing the ignition lockout. It's a 1974 Dart with a 360LA. It was running fine before we swapped out the 50 year old fuel line. There is gas getting to the carb, but no spark. I have a wiring diagram, but this plug isn't on it. It has a yellow wire, yellow/black stripe and a brown wire. The plug is red. Any thoughts on where that jumper was connected? I don't want to randomly plug in the jumper and fry something in the process.

Thanks in advance.
