I've posted this before.. here is a clear diagram and chart of the pin-outs for both the Craig and ASI radio harnesses. http://www.eskin.net/radioharness.html The commons are left/right, not front/rear, and in my case, with a new Alpine head unit, I had to tap into the individual speaker leads behind the radio (in the harness itself) in order to hook up all four grounds directly. I did use one of the wiring harness adapters, and it was useful for most connections, but if you're installing most modern radios, it WON'T be a plug and play affair due to the separate grounds. -Hank To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
