I missed your reply here SSpdDmon. Yes, of the many messages that have no help, yours made the wait worthwhile. Seeing the O2 circuit for the vette was the light switch so I could move forward. I want to thank you again for continuing to help me with the EFILive and the LM-1 WB kit. I have had this stuff lying around for years and with your knowledge and help from mvvette97 things are now rockin.
