Mechanic says I need a new engine wiring harness. Any ideas where to find one or have one made?

Why?
You can find one most likely from an auto dismantler (junkyard) who pulls engines and stores them in racks. Please reply to us all and tell us why the mechanic is saying why you need a new one.
Rodent damage. Bit through some of the wires near the connector to the pcm.
Good luck finding a useable undamaged harness for a 17 year old car brand that gm killed. You might look on carpart.com and see what is available.
It has been my experience that most harnesses can be repaired unless the connectors themselves are damaged. Can you post a picture of the damage?

A used one will do the trick, you can find them even this age in relatively good shape. Connectors are readily available to repair the old one but I can see the damage you have in my minds eye seeing the PCM is under the battery IIRC, that connector would be a real bugger to swap and repair wires close to the connector.
This is a 06, check the part# on yours and one of these, it will probably fit the 05, search for an 05 on that site also. A junkyard you can take your own stuff off is your best bet.

Your car probably uses a "E40" style PCM with the Delphi Micro Pack connectors, Not the easiest to field repair (As in removing pins & swapping wires)
The good thing is....These connectors have a plastic shield over them & unless the mice ate through the cover then ate some wires close to where they terminate?.....This should be easily repairable buy removing the shield/s giving the mechanic some wire length to work with.
