I have a Western Electric Touch Tone model 2554 BMP and the wire to terminal had to be removed in order to repair a broken wire. I fixed the broken wire, however, I have lost the wiring diagram designating which wire attaches to which terminal. I have tried several ways to get a copy of the wire to terminal diagram but have not had much luck getting a clear diagram. most I've gotten are fuzzy closeup pictures of the terminal block with a spaghetti mess of blurry wires attached in low resolution. I've identified the Terminal Screws inside my phone as: S, T, L1, F, A, X, R, G, GN, L2, B, RR, C. The wires are divided into the following groups: SwitchHook : Green, White, Red, Brown, Black, Yellow, Grey; Ringer : Black, Red, Grey, Grey/Red; Handset : Red, Green, Black, White; Keypad : Green, White, Red, Black, Blue, Red/Green, White/Blue, Orange/Black; Line : Red, Green, Yellow (I know this wire is not used). If someone could tell me which wires attach to which terminals, I'd really appreciate it greatly. Thank You.

Here you go:

(Note that most terminals will end up with multiple leads connected to them).

Switch hook leads:

Yellow and slate go to L2.
Green goes to L1
White goes to F
Brown goes to C
Red goes to R
Black goes to S

Ringer leads:

Black goes to L1
Red goes to L2
Slate goes to A
Slate/red goes to K

Handset leads:

Black goes to B
Red goes to T
White goes to R
Green goes to S

Dial:

Green goes to F
Red goes to T
Red/green goes to R
Blue goes to B
White goes to GN
Orange/black goes to C
White/blue goes to S
Black goes to RR

Line jack:

Green goes to L1
Red goes to L2
Yellow goes to G
Black goes to X or may simply be insulated and stored.

There may be some variations depending upon the dial type that you have, but that should work.

Ed...this a great cheat sheet to have. Thanks!

Thank you, the wiring diagram works and the phone is functioning fine.

Glad to help and thanks for letting us know the outcome. Come back around here anytime. Broken toaster? No problem.
