To actually answer your question, no you don't HAVE to have one. But it makes things much much easier if you do.

when ur HU got jacked, did they leave part of the wiring harness that is attached to the car? or did they cut it off from the harness leaving you with just bare wires? if it's bare wires...... a wiring harness won't help you any, its designed to plug into the harness that is no longer there.....
