there is a diagram of the moon&tunes setup at
http://forums.genvibe.com/zero...o.gif but that is more useful for the wiring to the amp than to the head unit. The pdf I attached is from an earlier Matrix, but the wiring in it is the same for a Vibe.It's too late now, since you already cut the connector off of the factory radio harness, but for next time, or for anyone else, they sell adapters, a connector that plugs up with the factory harness and provides individual wires, and you can then use that to connect to the adapter pigtail that comes with the new head unit. Using something like that allows you to build an adapter that will plug into the unmodified car wiring and to the new head unit. I hate cutting wires in the car harness, and using one of thise things would allow you to put the original radio back in quickly.There are a lot of threads here at genvibe about wiring up aftermarket radios in these cars, search through the Audio/Electronics forum. Hopefully some will help, although if the cut wire harness has a number of the same size wires with the same colors, you could be in for some tedious trial and error.My guess is that you blew the DOME fuse, which is in the underhood fuse block.
