where does the hot wire come from going to the distributor on a chevy 350
Bad plug, bad wire, bad distributor cap or bad valve.

The number #1 plug is the forward-most plug on the left (driver's) side. Trace that wire back to the cap and you've got your answer.
you don't it has a coil pack
It is in the very back of the engine. Just follow a plug wire from the spark plug to the distributor cap. It is hard to see. All the plug wires start at the distributor and then hook to each plug.
You need to run a switched, full-voltage wire to the "bat" terminal.
no1 on the distributor always points towards the no one cylinder
negative side of coil, or if electronic distributor it will have a port on the distributor, then its power wire and ground and then same for lights
What year the vehicle is would be helpful and what engine you have.
