1. A bulkhead for transmitting detonation signals, comprising:
an elongated tubular body having a first end, a second end opposite the first end, and a bore extending from the first end to the second end;
a signal pin residing within the bore of the bulkhead, the signal pin also having a first end, and a second end opposite the first end and configured to transmit electrical signals from the first end to the second end;
an electrically conductive wire connected to the second end of the signal pin within the bulkhead; and
an end piece integral to and extending from the second end of the bulkhead, closely and frictionally holding the conductive wire in place;
wherein the first end of the signal pin resides proximate the first end of the tubular body to receive the electrical signals, while the second end of the signal pin resides proximate the second end piece of the tubular body to deliver the electrical signals.
