That looks awesome. Good luck with the sale. Some lucky person is going to end up with a very unique car.If I may ask, what was the issue with the engine wiring harness? Is this something that other C6 and/or Z06 owners should look out for? Seems a little unusual that a mass produced GM car would need this renewing at ~10yrs and low mileage.
Cheers,
Tim

The wiring issue first came to light when an error code from the throttle body position sensor highlighted a cable that had come apart. It had broken within the protective cable shroud . . . Initially that cable was replaced but during the very long and expensive process of finding this cable a good number of other wires and connectors were found to be loose to the point of potential failure. I took the decision to have the engine rewired by Silec Motorsport wiring who did an amazing job and made the whole job look so neat and tidy. They managing to remove a lot of block type connectors many of which were on the ignition wiring. The end result made a noticeable difference to the crispness of the engine, yielded an increase in power when the car went back on the dyno, and to this day no further error codes have been triggered. The experts view was that the wiring was of a low quality, too tight in places to allow for engine movement, and that the harness was not adequetly protected from heat and potential friction points, hence the problem. I know of another few owners in the UK who have done the same. If that first initial wire had not broken I guess I would not have done anything so I would not worry if you have a Corvette and it has no problems. The fix was under £1k and took a week or so.

Very interesting, thanks for the explanation. I thought i had heard of others having similar re-wiring jobs.The wiring issue first came to light when an error code from the throttle body position sensor highlighted a cable that had come apart.

Definitely a quality issue then. I suspect this is also not unique in the industry with everyone using the same wiring suppliers, and everyone squeezing costs.
