@TRcustomengineering It was an unusual problem. We also felt it was a good lesson on how the ignition system functions. We learned from the experience, hope you did too.

ALDL Assembly Line Diagnostic Link

DLC Diagnostic Link Connector

Yes DLC came about at the beginning of OBDII, they are both used today and mean the same. I hope you enjoyed the video and understood it's true meaning.
