Default LS6 Engine Wiring Harness Replacement

The wiring harness on my LS6 has become very brittle and the wires are very prone to breakage. Will any harness that fits the LS1 also work for the LS6?

In that vein, does anybody see a reason why
this harness this harness
couldn't work?

That's a drive by cable harness for the throttle body. Corvette's are drive by wire

Shoot, glad I asked you guys!

Are there any replacements on Amazon or somewhere else for relatively cheap? Anything would be better than the harness that’s in there.

There are some differences in years, and there are some differences between manual and auto transmission harnesses. You didn't say what year your Z06 is, but a similar year LS1 manual harness should be awfully close. Remember the fuel system changed for 2003.5 to 2004.

it’s a 2002 Z06, so obviously a manual. Forgive me as I don’t know the transmission names, but would something like this work?

It says that one is for a 4l60e, so automatic transmission. You will have a much easier path if you get a C5 harness. The transmission is at the back of the car. Try placing a post in the C5 parts section.
