Aftermarket radio in stock cd changer location?

[Keymaster]

Has anyone installed an aftermarket radio in the cd-changer location. I have an 02 Escalade which had the changer right above the ash-tray. I pulled it all apart this evening real quick and was able to pull the changer out. It looks the exact size of my Pioneer deck. I would love to keep the factory radio in it's stock location and install the Pioneer in the cd changer location to keep it looking somewhat stealth. My biggest concern is, will the harness reach down to that location? I have the harnesss to connect an aftermarket deck to the factory wiring, so the wires may reach. I just didn't have time to see if there were any obstructions between the radio and the changer location.

Thanks
