GM – Corvette Appendix
Neo Changer Connection to
Chevrolet Corvette
Most Corvettes are pre-wired to the trunk. In case you can’t find the connector in the
trunk, please do the following:
1. Preparing the Neo GM-A Cable
Take the Neo GM-A cable and cut off the Black and Red harness, you will then
have two cables in your hands. One cable with the big white 22 pin connector
and 1 with a small white 9 pin connector. You will use only the cable with the big
White 22 pin connector (connects to the black box).
2. Connection to the Vehicle
There are two connectors located behind the radio, one is black and the other is
grey. We will first work with the grey connector.
