Yup, your gonna need the schematic.
In the upper left corner, are all the misc connections.
There again, you will need to find a component, and trace the wires.
I think there is a filter cap in the primary power circuit.
And a switch on the board to turn on/off power.??
those are the two things that will help you find the right connections.
Which will get you started...Then the fun starts!!!

Good Luck with all that wiring. Have you checked all the documentation I have stored on Google? The shematic should be in there.

Have you checked the TCI library?
Search WE 555 switchboard using the google search option. I found 146 items.

I am making progress on tracking the MISC Terminal Block wires back into the interior of the Switch Board controls.  However per SD-66520-01-G2 diagram the wire from terminal 16 goes to "IM (NL) REL." it is a RED wire at Terminal Block.  Can somebody tell me what "IM (NL) REL." means and where to find it.  Thank you.  Jim

My last post didn't get posted.  I don't know why.  Maybe files too big or something so I will send files in separate posts.
See the second to last page in the SD-66520 document.  Terminal 16, where do I find the internal switchboard end of that wire? The document T-66520 may help but the wire goes to a heavy solid line and I have no idea where it goes inside the switchboard from there.  Please remember that the Terminal Block "MISC" had been completely disconnected and removed.  That leaves me with having to trace the wires back inside the switchboard to determine which one use to go to terminal 16 from the internal switchboard to the terminal block.  I also am having trouble finding the wires that use to go to terminals 43,44,45,46,47 and 48, where do they come from?  The SD-66520 indicates they come from things like "LT. PAN".  What is that and where do I find them and how do I get to them? Any help you can give me is appreciated.   Jim

I can't get the internal wiring document to post.  It is in the link provided by Harry Smith above https://drive.google.com/drive/folders/0B6eDAxemj1VHZjk2NTgwNWItMGUzNy00YzhhLWI4NGQtNzc3MTU4OGE5MjRh   Please see document T-66520-38.gif  Thank you.   Jim

Hmm??? post hasn't shown up???
Abridged version...
Pin 16 to OUTGOING side of BATT switch. The input side has a 125 uf capacitor "-" tied to it. This comes from the BATT
Pins 43-48 are ground RETURNS...
That means they terminated there, and were jumpered at the MISC block... They arn't now... They need to be. Do that later.
GROUND may be found at the "+" point of the 125uf capacitor. in fact, that may be a good place to find and use as reference.
