123 ignition tumbler wiring

hello everybody, my ignition tumbler housing just broke yesterday and it is something internal. the key will turn but there is no response whatsoever. i was able to drive it home because the sterring wheel will unlock but no electical power to every sysytem in the car. no headlights, turn signal lights, brake lights, no ac/heat, cant roll the windows down, etc. but i was able to hot wire the starter via the junction box on the passenger side inner fender wall.

anyway, i was able to pull the tumbler housing/assembly out of the dash and steering column but i have no choice but to break the wiring harness because the T would not line up to the slot to properly pull the electrical connection without breaking it.

now i dont know which wire goes to which. can somebody out there provide me a wiring diagram or any source of the ignition switch for my 1985 300D Turbo 123. does anyone know about the wire colors and which # on the electrical connector does it go.

any help will be appreciated! thanks in advance

Key Switch Wiring

Do you have the terminal numbers....I have a Haynes manual up to 84...They are probably close....
Are all of them unknown or do you have a few intact...?
They all seem pretty close on the schematics....as far as wire color and terminal#...
Somebody here probably has them...If not I can post what I have...
