EBL Bench Test

I'm planning on installing my GM TB EFI with EBL system later this year, but would like to get some practice with its operation while it's sitting on the bench. I have a harness with sensors attached. Which pins need power and ground to fire it up, load BINs, etc.? Any cautions?

Once I'm familiar with it, I plan on installing it for spark only, plus sensors, at first to try and solve a backfire through carb issue, then fuel when I can find enough time to make some intake manifold changes. Thoughts?

Also, while I can use the WUD display going down the road, can anyone recommend a modern gauge graphics program for display and alarm (not tuning). I assume this would utilize the ALDL port on the ECM to harvest the data.

Got it! A couple of the harness wires were a different color than the diagrams... Thanks.
