Question Where to Buy - Complete LB7 engine harness

I'm pulling my LB7 out to do some much needed maintenance. I've got a water leak that needs fixing. Manifolds need replacing. Probably going to slap a new turbo on it, too. Nothing crazy, but mine has just a hair of shaft play in it.

So, that being said, I want to replace my engine wiring harness while I've got the engine out of the truck. The current harness has seen better days. It has seen 18 years of tough winters, salt, dirt, oil, etc. A lot of the plugs are really loose and most of the loom is broken in more than a few places. So I want to just put a whole new harness in there.

My question to you - where to buy one? When I do a google search I get all kinds of things, but none of them seem to be for an LB7. Any ideas on where to start my search?

2003 Chevrolet 3500 DRW, LB& with forged rods and crank. Tuned. Lots of little odds and ends.

I know a whole lot about nothing. And I know nothing about even more.

To buy new, probably a dealer would be the easiest place-if its still available. But it wont be cheap I'm sure...

You could call Hicksville Auto Recyclers in Ohio but it will still be a used harness and who knows how many miles on it. They may have some in pretty good shape, but still used.
