Hey everyone, having a DBW pull your hair out moment here and was looking for some insight from those who have tackled this before. I got a 2005 LQ4 going into my S10 and just finishing up the wiring. I now realize how close you have to match the APP to the TAC and I got the wrong TAC from the wrecker, no biggie. My question is about the PCM. I have a serv # 12602802 hdw # 12589162 pcm with a vin that shows its a 2007 PCM. Now the 2007 has no TAC as the ECM has it built in. So my question is do I need to swap the PCM out to a serv # 12589463, or can I use this PCM I already have. I've searched for a while and pretty sure the PCM I have will work, just wanted to verify. Thanks!

Just flash the right file you want to match your TAC module you have. The file should fit into the pcms you are referencing just fine.
