[Gmecm] 88 Chevy S-10 Pickup -Fuel Injection Conversion on Jeep-

[Beau Blankenship]

I would almost guess that you are somewhere near me (Benton/Little Rock,
AR), but looking at the radar screen today, it looks like that description
pretty much applies to most of the country. If you had cut that wire, I
don't think you would have computer timing control. It looks like it goes
from D5 of the big ECM connector to pin B of the ignition module. If that
wire is not connected, the ECM will not control spark advance (so that you
can adjust the base timing.) <<basically what has already been said. Good
luck this weekend. I'm going to go out and un-strap the boat from the
trailer so it will float freely when the creek comes up. ;)

Ah, I will look into that... thanks a bunch!  I'll dig into the wires 
sometime in the near future (its going to be pouring outside for the 
next few days it seems like) and let you know what I find!
