I was hoping that I might be able to get the PCM pinouts for my car, more then anything I need to locate the cylinder one driver pin on the pcm plug. My PCM in my car has this number stamped on it 8T4A-12B684-BA
here is the vin # as well if that helps pinpoint the specific pcm being used

vin: 2LMDJ8JCXABJ09314
Thanks in advance

just for some context behind why I need this, I get the code p031 I believe is what it is or something similar to that, it says it's problem with circuitry with cylinder one, I've replaced the coil on cylinder one, I even bought a new pcm because I was told that that happens with the Lincoln occasionally that it gets shorted out and that cylinder one driver fries in the pcm. but I still get the same code now, so what I'm left with is it has to be in the wire or the plug end. I just want to be able to check continuity on that cylinder one wire from plug to plug.
