New Wiring, need help with diagrams

Hi all,

I am trying to finish the wiring with the ECM on a monte Carlo, this car had a gremlin eat all the wiring up...

I've been re-runing complete new replacement wires one at a time in the harnesses into the factory pluge, which is a tone of work without breaking anything, so far I have been able to match everything up..
(I do not have any service manuals of any kind for this car)

Once I get this car fully running again, I'll work on getting everything else correct, but my problem at the moment is the following trouble codes:
P1652
P1657

I'm getting these trouble codes from the ECM and I think that the P1652 is the second fan?
I do not know what the P1657 code refers to, I'm being told its a solenoid of some kind?
I think can find these components on the vehicle, but I can't find how to properly connect them to the ECM...

If someone could send me a wiring outline of the ECM plugs (White and blue) I would really appreciate it, I'm having trouble finding this online...
(Thank you for the help, I'll post my progress here) :)
