    Question Looking for a ECM for a old GMC Topkick

    Hi All
    I am trying to find a ECM for a 1993 GMC Topkick and not having much luck. The number on the one from the truck is 16147525. Every source I try tells me it's no longer available.
    If anyone here can direct me to a source for this it would be appreciated.


    Thanks.
    Al Eosso Sr

    Hello and welcome to the forum.

    That certainly is an old ecm. The number on your ecm was superceded by 88963805 which appears to be the same ecm as 16207326. Collectors Auto Oroville Blaine, WA 98230, does show one in stock http://collectorsautosupply.com/. 16147525 also crosses to an A1 Cardone 777525 but I don't know if it's actually available. There also seems to be one on Ebay right now: https://www.ebay.com/sch/i.html?_fro...63805&_sacat=0 .

    This page appears to show several shops selling an ecm with the 8896 number:
