hi - hope someone can help me!

I built a Yaffe framed, TC88B Harley motor custom (new 2005 carb motor). Its put together and it is all ready to go. All electrics work but it won't spark/start. Horn, lights, turn signals, brake lights. starter motor all work. I have a new Screamin Eagle ignition module for an '05 carb model. The coil is a working (supposedly) take off coil. I do NOT have a bank angle sensor. The SE ign module for an '05 has one, 12 pin connector. I used 11 of them; all except the "serial" input from the Turn Signal Module (which apparently houses the Bank angle sensor).

Question is; do I NEED a bank angle sensor input for the motor to spark?

Any suggestions on what to check first?

The motor is new. The crank position sensor is new and came with the motor.

Any help appreciated!
