Ecm identification

[thatguyHoBo]

Hello everyone, sorry if this is posted else where. I'm trying to identify what ecm I have in my truck. The sticker is so deteriorated all I can make out is "16136301" & "122". I drive a 91 k2500 5.7 tbi 700r4. Can I pull the ecm and verify the number on the memcal anywhere? I'll attach a picture of what I have so far.

If I had to guess, you have a 1227747 ECM. You can pull it out and remove the lid to see the BCC to match it up with one of these in this link.
