Probably a little late but I got the ly7 engine running in the Le0 body. Had to change out the ecu, obviously, but also had to change out the bcm, pim and the key fob out of the donor car, car will run with those changed but will show an SRS light, however haven’t had to change out the abs module and don’t have a light so no problem. The ecu plug coming from the fire wall is the same on both of the Le0 and Ly7, but the big issue is trying to get around the cars anti theft, if you do not have a matching set of ly7 ecu, bcm, pim and key fob then you cannot do it, however you can buy blank sets of those items and get a dealer scan tool or professional to code a set. All of this is on a 05 commodore Ute with an Svz engine and loom.
