No problem, I understand. That is why the system is setup to communicate back and forth until completed.
1. OK, so T2, P5, and T3 are all bound together with a wire nut. Do they connect to the chord in any way?
They do not connect to the cord, they only connect to each other.
2.The chord I will use will have three wires. Which color will connect to T2, T8, and T4?
Black will connect to these 3, that is the hot wire
3. Which color will connect to the P1 neutral?
White connects to P1, that is the neutral
This is based on a standard cord with black , white and ground wires.
You need #12 not #14 on the cord.
