Just a question. I know that eary models included an actual diagnostic socket and the later models did not but did provide a conector from the wire bundle. The diagnostic socket was never used and no diagnostic instrament was built. Section M:04:01 in the manual explains its function. My question is can the socket be used now if the conections were reinstalled and a diagnostic unit was built with todays technology. Would it be worth it to have it reinstated or the information it was intended to provide be useless. Thanks Ed
