This is exactly what I thought, thats what threw me. The number
that I posted was from memory, but I looked at that ECM several
times, reading out the number. I found it installed in the stock
location, so I don't think that it was swapped by someone in the
yard.

The other thing, is that the number started as '124...', not the
usual '122...'. And it was the service number I read. I also walked
around the van checking the shape and emblems, it was an Astro van.

Weird.

Maybe I'll just go back and get it.

Yep, these vans are where I've been getting the harness, sensors,
distrib, coil, ECM... for my swap. They are cheap and plentiful.
Heck, everything for a TBI swap is less than the price of a 
new carb.

See this, new info. OK, how about these 'templates', have any
info on the calibration layouts? Anyplace I can go for info?
