I use the same obd2 to obd1 conversion piece. I actually am using a stock obd2b harness.. converted all the plugs to obd1.. then had to modify that harness for the h22a1 engine when I got that. Turned out great. Good note is to make sure that conversion piece is plugged in snugged. My first start up didn’t happen because it wasn’t plugged in tight enough.

Yea for sure. Thought I mentioned that in the video to make sure its fully connected. I might have failed to mention it Idk but deff good advice.
