    on an 88 k-5 blazer the ECM that i removed from mine looks to be a non-original part, is their a way to tell if its GM or not?
    the numbers on the tag are SERV. NO. 1227747 AMUR 860061 E380981995

    1227747 ='87-'91 GM trucks. Looks like the right one to me. When you get one make sure to get one for the trans you have in your truck. Or you can swap your PROM chip into the new one.
    Why are you replacing the ECM? They dont go bad that often.
