pin out

  1. PCM pin out question

    PCM's & Tuning
    Hi, Is there anyone that can help me with the pin out on a 2001 Monte Carlo SS 3800? I had a top side fire, and need to make some repairs. I was told only a 01 or 02 Monte or Impala would work, I did find the info on a 3400 but unable to confirm if this would be the same. Thanks for any help...
