Hi, I have not posted in a while but im looking for some info. A while back I bought an ex Texas State Trooper car that was totaled, I then resold it, well just recently I bought back the drive train complete minus the car. I plan on using this setup in a hot rod but I cant seem to find any info on the ecm. I was not the one who removed it and it does not have any stickers or info on it. I would like to know what ecm it is and the pinout for it. Any and all help will be appreciated. I did try the search tool but I have limited info to work with.

1992 305 standard trans.
B4C,1LE

 

That would be the 1227730 ECM. Bottom of page for wiring:
