Voltage regulator chirp/not starting

[Breadstick]

I installed a painless wiring harness (part #10206) in my 72 C20 last weekend and it won't start. According to their instructions, wires 3 and 4 of the voltage regulator plug are jumpered together with the white wire spliced to them and to hook the F and R on the voltage regulator to the F and R on the alternator. There is a red power wire for the battery lug on the alternator and nothing goes from the alternator to the battery. I hooked everything under the hood except the lights up and the connections in the cab necessary to start the truck. When I turn the key I hear a very quiet chirp kind of sound from the voltage regulator but the starter doesn't try to start. Has anyone had this kind of issue before? Unfortunately, the customer service hours for painless are about the same as my work hours so I can't call them and ask.

I put a painless harness on my 85 C10 and it was MUCH better than this. I had a novel sized manual to go by and it was really detailed. The manual for my 72 is about 35 pages and the kit didn't even come with all the connectors I need for the install.

Here is the picture from the installation instructions for the charging system.
