Yes, you can transfer that board to another cluster and transfer the mileage. Somewhere in this thread someone agreed that they had done it succesfully.
Ok thanks. Does that green board control the DIC too? That's the problem I'm having right now. If not, i'll just buy a cluster on the auction site and transfer that board on my old cluster to the new one. Also does that chip come out or can I just swap boards?

Sorry, I wasn't implying anything. Most people wouldn't have a clue, so I apologize.

I'll just continue to sit here in my corner, with my donor Z06 cluster showing the proper mileage in my '99... continue the discussion.

And you swapped the main mother board NOT the smaller board correct?

Last weekend I tried swapping out the small board and it did not change the mileage, I think you need to swap the mother board and on the 97,98 and early 99s the mother board will not have the HUD connection

I didn't touch the smaller circuit board in either of my clusters...

Vet.mix and I have a 1998. So Anybody prior too 1999 cant just change out the board because we have non hud circuitry. So Go to a tech 2 person, and pay the few hundred bucks... I wish it was that little circuit board on the left, but oh well.

Also the check engine light has to be relocated too. Just too let you all know.

/\ Good info! FYI some earlier 99's may or may not have the HUD connector.

I think you mean the Airbag light has to be moved, not the CEL.

I had the same problem with my cluster so I bought a new one that worked, swapped in the board behind the fuel gauge from the cluster that didn't work and the DIC still worked and the mileage was still the same. Has this worked for anyone?
