I had worked on a 2002 Z06 a few years ago, and left my roadrunner installed in his car for about 1 year and finally got it back from him about a year ago but it was missing the USB cable. A few months ago, I ordered a new one, and I went to use it on another 2003 Z06 today and it did not work. I could connect with the USB cable and was able to communicate, but no connection to the OBD2 port.

I decided to take it apart to see if the board has come loose, but that was not the case. Somehow, water had damaged the ECM, and there was corrosion all over the triacs and all over the case. Fortunately it looks like the roadrunner may still be ok, but the stock ECM is likely toast.

A few things I noticed, the board is a 1999-2000 ECM, not a 2001-2002 as I thought it would have been.

Anybody know the part number of the 44 pin header? I hate to pay $8.00 to ship a $10 part and will be placing an order with mouser or digikey in the next couple of days?

I do not know if the through case connector can be salvaged, or if it is toast as well, there is lots of corrosion growing on it.

Thanks,

Ryan
